Question

3. A car starts a trip with 20 gallons of gas in its tank. The car traveled at an average

speed of 65 miles per hour for 3 hours and consumed gas at a rate of 30 miles per
gallon. What percent of the gas in the tank was used for the 3-hour trip?​

Answer 1

32.5%

Explanation:

first we will have to calculate how much miles the car traveled, to do that we will multiply the speed by hour long the car was traveling for which is

65*3=195

During those 195 miles the car used 1 gallon for every 30 miles which means it used 6.5 gallons of its tank

195/30=6.5

6.5 gallons is 32.5% of 20 gallons

6.5/20=0.325

0.325 * 100 = 32.5%
