Terry drives at a speed of 40 miles per hour. He drives daily forth and back from his home to his workplace which is 60 miles away from his home. How many hours does Terry spend driving from home to the workplace and then back?

The miles that Terry drives daily from home and back are 60 * 2 =

<<60*2=120>>120 miles. The hours he takes driving from home and back are 120 / 40 = <<120/40=3>>3 hours. #### 3 Jerry was contracted to work on a house by his neighbor Miss Stevie. The time it took him to fix the broken kitchen counter was three times longer than the time he took painting the house. He took 8 hours painting the house and then helped mow Miss Stevie's lawn, taking 6 hours. If he charged Miss Stevie $15 per hour of work, calculate the amount of money that Miss Stevie paid him. Jerry took 2*8 = 24 hours fixing the broken kitchen counter Together, painting the house and fixing the broken kitchen counter took him 24+8 = <<24+8=32>>32 hours. If he also took 6 hours mowing the lawn, the total time he spent working for Miss Stevie is 32+6 = <<32+6=38>>38 Since he charged $15 per hour of work, he was paid 38*$15 = $<<38*15=570>>570 #### 570 Bob and Johnny have a leaf raking business. They charge $4 for each bag of leaves they rake. On Monday they raked 5 bags of leaves. On Tuesday they raked 3 bags of leaves. On Wednesday, they counted their money and found they had $68 for all three days. How many bags of leaves did they rake on Wednesday? Combining Monday and Tuesday, they raked 5 + 3 = <<5+3=8>>8 bags of leaves. They earned 8 * $4 = $<<8*4=32>>32 for the first two days. O for Wednesday's work they earned $68 - $32 = $<<68-32=36>>36. Thus, they raked $36 / $4 = <<36/4=9>>9 bags of leaves on Wednesday. #### 9 Barbara Blackburn can type 212 words per minute. Due to Carpal tunnel syndrome, Barbara cannot use her left hand for a while so her typing speed is now 40 words less per minute. If she is supposed to type a document with 3440 words, how many minutes will it take her to finish typing the document? Due to carpal tunnel syndrome, Barbara can only type 212 - 40= <<212-40=172>>172 words per minute. So, she will be able to finish typing the document in 3440/172 = <<3440/172=20>>20 minutes. #### 20 A tree had 1000 leaves before the onset of the dry season, when it sheds all its leaves. In the first week of the dry season, the tree shed 2/5 of the leaves. In the second week, it shed 40% of the remaining leaves. In the third week, the tree shed 3/4 times as many leaves as it shed on the second week. Calculate the number of leaves the tree hadn't shed by the third week. In the first week, the tree shed 2/5*1000 = <<2/5*1000=400>>400 leaves. The number of leaves remaining on the tree at the end of the first week is 1000-400 = <<1000-400=600>>600 In the second week, the tree shed 40/100*600 = <<40/100*600=240>>240 leaves. The number of leaves remaining on the tree is 600-240 = <<600-240=360>>360 The third week the tree shed 3/4 of its leaves, a total of 3/4*360 = <<3/4*360=270>>270 leaves. The number of leaves remaining on the tree is 360-270 = <<360-270=90>>90 leaves. #### 90 Nancy takes 3 antacids per day when she eats Indian food, 2 antacids per day when she eats Mexican food, and 1 antacid per day otherwise. If Nancy eats Indian three times a week and Mexican twice a week, how many antacids does she take per month? First find the total number of antacids Nancy takes after eating Indian food per week: 3 antacids/day * 3 days/week = <<3*3=9>>9 antacids/week Then find the total number of antacids Nancy takes after eating Mexican food per week: 2 antacids/day * 2 days/week = <<2*2=4>>4 antacids/week Then find the number of days she doesn't eat Indian food or Mexican food: 7 days/week - 3 days/week - 2 days/week = 2 days/week Then find the total number of antacids Nancy takes per week: 9 antacids/week + 4 antacids/week + 2 antacids/week = <<9+4+2=15>>15 antacids/week Then multiply her weekly antacid consumption by the number of weeks per month to find her monthly consumption: 15 antacids/week * 4 week/month = <<15*4=60>>60 antacids/month #### 60 Two buses leave a pick-up point station with 60% and 70% of capacity full, respectively. If the people in the buses are all employees of a company, and the buses have a capacity of 150, calculate the total number of the employees in the two buses combined? If the first bus is 60% full, it has 60/100*150 = <<60/100*150=90>>90 passengers. The second bus is 70% full, meaning it has 70/100*150 = <<70/100*150=105>>105 passengers. The total number of people in the two buses is 105+90 = <<105+90=195>>195 #### 195 Bobby has an aquarium with twice as many fish as Sarah's has. Sarah has 5 more fish in her aquarium than Tony does. Tony has 3 times as many fish in his aquarium as Billy does. Billy has 10 fish. How many fish do all 4 people have put together? Since Tony has 3 times as many fish as Billy's 10, that means Tony has 3*10= <<3*10=30>>30 fish Sarah has 5 more fish than Tony's 30, meaning she has 5+30= <<5+30=35>>35 fish Bobby has twice as many fish as Sarah does, meaning he has 35*2=<<35*2=70>>70 fish Therefore, altogether there are 10+30+35+70=<<10+30+35+70=145>>145 fish #### 145 Andrew's father buys a package of 100 masks. Andrew lives with his 2 parents and 2 siblings. All members of Andrew's family change masks every 4 days. How many days will it take to finish the pack of masks? Andrew's family consists of 1 + 2 + 2 = <<1+2+2=5>>5 people. Each of Andrew's family members uses 100 masks / 5 = <<100/5=20>>20 masks. With everyone wearing a mask every 4 days, the masks will last 20 masks * 4 days/mask = <<20*4=80>>80 days. #### 80 Carlos read 28 books in July and 30 books in August. He needed to read 100 books during his summer vacation. If Carlos read some of the books in June, calculate the number of books that Carlos read in June to meet his goal? Carlos read 28 books + 30 books = <<28+30=58>>58 books. He needed to read 100 books - 58 books = <<100-58=42>>42 books in June. #### 42
