Question

Hassan loves cruising in his new sports car. His only complaint is how much gas it uses, since it only gets 20 miles per gallon. If Hassan drives 60 miles per hour, how many gallons of gas does his car need for a 75-minute drive?

Answer 1

3.75 gallons

Explanation:

speed = distance/time

s = d/t

d = st

d = (60 mi/hr) * (75 min) * (1 hour)/(60 min) = 75 miles

In 75 minutes of driving at 60 mph, he drives 75 miles.

fuel economy = distance/volume

volume * fuel economy = distance

volume = distance/(fuel economy)

volume = (75 miles)/(20 miles/gal)

volume = 3.75 gallons

Answer: 3.75 gallons
