Police officer A patrols 36 streets in 4 hours. His colleague, officer B, patrols 55 streets in 5 hours. How many streets will both officers patrol in one hour?

How many streets does officer A patrol in one hour? ** Officer A patrols 36 streets / 4 hours =

<<36/4=9>>9 streets/hour. How many streets does officer B patrol in one hour? ** Officer B patrols 55 streets / 5 hours = <<55/5=11>>11 streets/hour How many streets will both officers patrol in one hour? ** Together officer A and B patrol 9 streets/hour + 11 streets/hour = <<9+11=20>>20 streets/hour. #### 20 Jim has a pail with rocks in it. The average weight of a rock is 1.5 pounds. A local rock collector agrees to pay him $4 for every pound of rocks. If he makes $60 off the sale, how many rocks were in the bucket? How many pounds of rocks were in the bucket? ** There were 15 pounds of rocks in the bucket because 60 / 4 = <<60/4=15>>15 How many rocks were in the bucket? ** There were 10 rocks in the bucket because 15 / 1.5 = <<10=10>>10 #### 10 In a field where there are 200 animals, there are 40 cows, 56 sheep and goats. How many goats are there? How many animals are there other than goats? ** We have 56 + 40 = <<56+40=96>>96 animals other than goats. How many goats are there? ** So, we have 200 – 96 = <<200-96=104>>104 goats #### 104 If a basket is capable of holding 40 fruit altogether, and there are 3 times as many apples as oranges, how many oranges are there? How many apples are there? ** Since the ratio of apples to oranges is 3:1, that means for every 3 apples there is 1 orange. The size of this group is therefore 3+1=<<3+1=4>>4. How many groups are there? ** We then divide this group size into the total amount of fruit the basket is holding at this time, which is 40. This means there are 40/4=<<40/4=10>>10 of these groups in total. How many oranges are there? ** Since there are 10 of these groups in total, that means there are 10*1=<<10*1=10>>10 oranges in the basket. #### 10 Rodney and Todd are rowing down a river that is 50 yards wide at one end. If the river's width increases from this end uniformly by 2 yards every 10 meters along, and they row along the river at a rate of 5 m/s, how long (in seconds) will it take them to get to the point where the river is 80 yards wide? How many yards wider is the river at their destination? ** The difference in width between where they're starting from and their destination is 80-50 = <<80-50=30>>30 yards How many meters do they have to cover? ** The width increases 2 yards every 10 m along the river so they would have to cover (30/2)*10 = <<(30/2)*10=150>>150 meters How long will it take him to cover the 150 meters? ** Traveling at the rate of 5m/s, he will spend 150/5 = <<150/5=30>>30 seconds #### 30 In two years, Ophelia will be four times as old as Lennon. If Lennon is currently eight years old, how old is Ophelia? How old will Lennon be in two years? ** In two years, Lennon will be 2+8 = <<2+8=10>>10 years old. How old will Ophelia be in two years? ** Ophelia will be 4*10 = <<4*10=40>>40 years old in two years. How old is Ophelia currently? ** Currently, Ophelia is 40-2 = <<40-2=38>>38 years old. #### 38 For football season, Zachary wants to buy a new football, a pair of shorts, and a pair of football shoes. The ball costs $3.75, the shorts cost $2.40, and the shoes cost $11.85. Zachary has $10. How much more money does Zachary need? How much does Zachary need to spend? ** The total cost of the ball, the shorts, and the shoes is $3.75 + $2.40 + $11.85 = $<<3.75+2.4+11.85=18>>18. How much more money does Zachary need? ** Zachary needs $18 − $10 = $8 more. #### 8 John buys 1.5 ounces of silver and twice as much gold. The silver costs $20 per ounce. The gold is 50 times more expensive per ounce. How much does he spend on everything? How much does the silver cost? ** He buys the silver for 1.5*$20=$<<1.5*20=30>>30 How much does the gold cost? ** He bought 1.5*2=<<1.5*2=3>>3 ounces of gold How much is the gold worth? ** The gold is worth %20*50=$<<20*50=1000>>1000 per ounce How much does he spend on gold? ** So he buys 3*$1000=$<<3*1000=3000>>3000 on gold How much does he spend on everything? ** So he spent $30+$3000=$<<30+3000=3030>>3030 on everything #### 3030 A lorry is 500 pounds when empty. What will its weight be if it's loaded with 20 bags of apples, each weighing 60 pounds? How many pounds will the lorry be loaded with? ** If the lorry is loaded with 20 bags of apples, each weighing 60 pounds, it will have an additional weight of 20*60=<<20*60=1200>>1200 What will the lorry weigh after being loaded with the bags of apples? ** The total weight of the lorry after being loaded with the bags of apples will be 500+1200=<<500+1200=1700>>1700 pounds #### 1700 Mikaela was repainting her bathroom.
