[Question]Before Marcus went on a road trip to LA, his car had 1728 miles on it. He filled his empty gas tank twice and used up all the gas on the trip. If Marcus's car gets 30 miles per gallon and holds 20 gallons of gas, how many miles does Marcus' car have on it now?
[Answer]First, figure out how many gallons of gas Marcus bought by multiply the gas tank's volume by the number of fill - ups: 20 gallons * 2 = 40 gallons. Then multiply that number by Marcus's fuel mileage to find how many miles he drove: 40 gallons * 30 miles / gallon = 1200 miles. Then add that amount to the initial number of miles on Marcus' car to find the final number of miles: 1728 miles + 1200 miles = 2928 miles. The answer is 2928.
Q: Lilly and Fiona are cleaning a room. Between them, it takes 8 hours to clean the room. A quarter of the time spent cleaning was by Lilly and Fiona was responsible for the rest of the cleaning. How long, in minutes, was Fiona cleaning?
A: Lilly cleaned for 8 hours / 4 = 2 hours. This means that Fiona was cleaning for 8 hours total cleaning 2 hours Lilly's cleaning = 6 hours. So in minutes, Fiona was cleaning for 6 hours * 60 minutes in an hour = 360 minutes. The answer is 360.
Question: Jake's dad can drive the distance from their house to the water park in 30 minutes. He spends half that journey driving 28 miles per hour and the other half driving 60 miles per hour on the highway. If Jake can bike 11 miles per hour, how many hours will it take him to bike to the water park?
Answer: First find how long half Jake's dad's trip is: 30 minutes / 2 = 15 minutes. Then convert the minutes to hours: 15 minutes * 1 hour / 60 minutes = .25 hours. Now find how far Jake's dad travels at 28 miles per hour: .25 hours * 28 miles per hour = 7 miles. Then find how far Jake's dad travels at 60 miles per hour: .25 hours * 60 miles per hour = 15 miles. Now add those distances to find the total distance to the water park: 7 miles + 15 miles = 22 miles. Now divide the total distance by Jake's speed to find how long it takes him: 22 miles / 11 miles / hour = 2 hours. The answer is 2.
[Question]Joe goes camping with his dad on a Friday. Joe's dad has 21 marshmallows, and Joe has four times as much marshmallows as his dad. If Joe's dad roasts a third of his marshmallows, and Joe roasts half of his marshmallows, how many marshmallows did they roast in total?
[Answer]Joe's dad roasts 21 / 3 = 7 of his marshmallows. Joe has 21 * 4 = 84 marshmallows. Joe roasts 84 / 2 = 42 of his marshmallows. Joe and his dad roasted 7 + 42 = 49 marshmallows in total. The answer is 49.
[Question]Every year, four clowns and thirty children go on a carousel. This year, the candy seller, at the carousel, had 700 candies. The candy seller then sold 20 candies, to each of the clowns and the children, who attended. How many candies did he have left?
[Answer]
Since there are four clowns at the carousel this year, the candy seller sold 20 * 4 = 80 candies to all the clowns. The thirty children also bought 20 * 30 = 600 candies in total. Altogether, the candy seller sold 600 + 80 = 680 candies to the clowns and children at the carousel. The number of candies the candy seller has left is 700 - 680 = 20. The answer is 20.
