Kevin's car can go 315 miles on one tank of gas he used just under 40% of a full tank of gas to get to a sporting event traveling at an average speed of 60 miles an hour about how long did it take him to get there

2.1 hours

Step-by-step explanation:

There is a direct proportionality relationship between the distance covered and the gas consumed. As such as the distance covered increases, so does the gas consumed.

If one tank will be used up in 315 miles, then 40% of the gas is consumed in

= 40% * 315 miles

= 126 miles

Distance is the product of speed and time.

If 126 miles is covered at a speed of 60 miles per hour,

Time taken = 126/60 = 2.1 hours

40% of 315 miles is 315 x 0.40 = 126 miles.

This means he drove 126 miles to get to the event.

He drove at 60 miles per hour, so divide the miles by the speed:

126 miles / 60 miles per hour = 2.1 hours (2 hours and 6 minutes)
