Q: A bus has a capacity of 200 people. If it carried 3/4 of its capacity on its first trip from city A to city B and 4/5 of its capacity on its return trip, calculate the total number of people the bus carried on the two trips?
A: From city A to city B, the bus carried 3 / 4 * 200 = 150 passengers. On the return trip, the bus carried 4 / 5 * 200 = 160 passengers. In total, the bus carried 160 + 150 = 310 passengers. The answer is 310.
Question: A fox can run at the maximum speed of 50 kilometers per hour. Considering the fox would run at a constant speed, what distance would he make during 120 minutes?
Answer: 1 hour is 60 minutes, so 120 minutes is 120 / 60 = 2 hours. During one hour a fox can make 50 kilometers, so during two hours, he would be able to run 50 * 2 = 100 kilometers. The answer is 100.

A: First find how many ml of water Jason needs for 1 gram of charcoal: 30 ml / 2 grams = 15 ml / g. Then divide the amount of water Jason uses by the amount of water per gram of charcoal to find how much charcoal he uses: 900 ml / 15 ml / g = 60 g. The answer is 60.
Question: Greta, George and Gloria entered their turtles in the Key West Turtle Race. Greta’s turtle finished the race in 6 minutes. George’s turtle finished 2 minutes quicker than Greta’s. Gloria’s turtle took twice as long as George’s turtle. How long did it take Gloria’s turtle to finish the race?
Answer: George’s turtle finished 2 minutes quicker than Greta’s so 6 - 2 = 4 minutes to finish. Gloria’s turtle took twice as long as George’s turtle, who finished in 4 minutes so 2 * 4 = 8 minutes. The answer is 8.
Q: Jessica wrote a long letter to her aunt and needed to put stamps on it to mail it. She used eight pieces of paper that weigh 1/5 of an ounce each, and her envelope weighs 2/5 of an ounce. She needed one stamp per ounce. How many stamps did Jessica need to mail her letter?
A:
Jessica’s papers weigh 8 * 1 / 5 = 8 / 5 ounces. The papers in the envelope weigh 8 / 5 + 2 / 5 = 10 / 5 = 2 ounces. Thus, Jessica needs 2 * 1 = 2 stamps to mail her letter. The answer is 2.
