Milo can roll downhill on his skateboard at twice the speed that he can run. And Milo's best friend, Cory, can drive his wheelchair at twice the speed that Milo can roll downhill on his skateboard. If Cory always drives his wheelchair at 12 miles per hour, how many miles can Milo run in two hours?

Since Cory drives his wheelchair at 12 miles per hour, then Milo rolls downhill on his skateboard at 12/2 =

<<12/2=6>>6 miles per hour. Therefore, Milo runs at 6/2 = <<6/2=3>>3 miles per hour. If Milo runs for 2 hours at 3 miles per hour, then Milo will travel 2 * 3 = <<2*3=6>>6 miles. #### 6 A bird eats 7 berries a day. Samuel has 5 birds. How many berries do Samuel's birds eat in 4 days? A bird eats 7 x 4 = <<7*4=28>>28 berries in 4 days. So, 5 birds can eat 28 x 5 = <<28*5=140>>140 berries in 4 days. #### 140 A banana tree has 100 bananas left after Raj cut some bananas from it. If Raj has eaten 70 bananas and has twice as many remaining in his basket, how many bananas were on the tree initially? If Raj has eaten 70 bananas in the basket, he has 2*70 = <<70*2=140>>140 bananas. The total number of bananas that Raj cut from the tree is 140+70 = <<140+70=210>>210 On the tree initially were 100+210 =<<100+210=310>>310 bananas. #### 310 Jim spends 8 hours scuba diving. In that time he finds a treasure chest with 100 gold coins in it. He also finds 2 smaller bags that have half as much gold each. How much gold does he find per hour? The smaller bags each have 100/2=<<100/2=50>>50 gold coins each So in total, they have 50*2=<<50*2=100>>100 coins So he found 100+100=<<100+100=200>>200 coins So he finds 200/8=<<200/8=25>>25 coins an hour #### 25 Tom fills a 250 pound sandbag 80% full. But the filling material he is using is 40% heavier than sand. How much does the bag weigh? The bag full of sand would weigh 250 * .8 = <<250*.8=200>>200 pounds The filling material would make it 200 * .4 = <<200*.4=80>>80 pounds heavier So it weighs 200 + 80 = <<200+80=280>>280 pounds #### 280 Michael wants to dig a hole 400 feet less deep than twice the depth of the hole that his father dug. The father dug a hole at a rate of 4 feet per hour. If the father took 400 hours to dig his hole, how many hours will it take for Michael to dig a hole that is 400 feet less than twice as deep as his father's hole working at the same rate? Since the father dug a hole with a rate of 4 feet per hour, if the father took 400 hours digging the hole, he dug a hole 4*400 = <<4*400=1600>>1600 feet deep. Twice the depth of the hole that Michael's father dug is 2*1600 = <<2*1600=3200>>3200 feet Michael wants to dig a hole 400 feet less than twice the depth of the hole that his father dug, meaning he wants to dig a hole 3200-400 = 2800 feet deep. To dig a hole that is 400 feet less than twice as deep as his father's hole working at a rate of 4 feet per hour, Michael will have to work for 2800/4 = 700 hours. #### 700 At the Sterling Auto Store, they have 500 cars for sale. If they have 10 sales professionals, and each salesperson sells 10 cars per month, how many months will it take for them to sell all of the cars? If 10 sales professionals each sell 10 cars per month, then they sell a combined 10*10=<<10*10=100>>100 cars per month. If the store has 500 cars, then it will take the sales team 500/100=<<500/100=5>>5 months to sell all of the cars. #### 5 On his calculator, August had solved a math problem with an answer of 600. The following math problem had an answer twice as big as the answer of the first math problem, and the third math problem had an answer 400 less than the combined total answers of the first and the second math problems. What's the total of August's answers from solving the three math problems on his calculator? August solved a math problem that had an answer twice as big as the answer of the first math problem, meaning the next answer was 600*2 = <<600*2=1200>>1200 The first math problem and the second math problem has answers totaling 1200+600 = <<1200+600=1800>>1800 The third math problem had an answer 400 less than the combined total answers of the first and the second math problems, meaning the third answer was 1800-400 = <<1800-400=1400>>1400 Altogether, the math problems that August solved on his computer had answers totaling 1800+1400= <<1800+1400=3200>>3200 #### 3200 The New York City Council bought 200 streetlights to modernize its squares. But they don't have enough squares to use all the streetlights bought. Knowing that there are 15 squares in New York and that each park will have 12 new streetlights bought by the city council, how many unused streetlights will remain? So the total number of streetlights that will be used is 15 squares * 12 streetlights/square = <<15*12=180>>180 streetlights There will be 200 streetlights - 180 streetlights = <<200-180=20>>20 streetlights unused. #### 20 Trevor and two of his neighborhood friends go to the toy shop every year to buy toys. Trevor always spends $20 more than his friend Reed on toys, and Reed spends 2 times as much money as their friend Quinn on the toys. If Trevor spends $80 every year to buy his toys, calculate how much money in total the three spend in 4 years. If Trevor spends $20 more than Reed every year to buy toys, Reed spends $80-$20 =$60. Since Reed uses $60 every year to buy toys, his friend Quinn uses 60/2 = $<<60/2=30>>30 every year to buy toys. The total amount of money the three spend in a year together to buy toys is $30+$60+$80 = $<<30+60+80=170>>170. The total amount of money the three will use to buy toys in 4 years is $170*4 = $<<170*4=680>>680. #### 680
