Question

Kevin drove his car to a concert. His car can go 400 miles with a full tank of gas. He used 30% of the full tank of gas to get to the concert while traveling 60 miles per hour

Answer 1

2.0 h

Explanation:

The question is missing but I think it is: "how long did it take kevin to get to the concert?"

Kevin can drive 400 miles with a full tank. If a uses 30% of the tank, he drives 30% of 400 miles = 120 miles.

The speed (v) of the car is the distance traveled (d) divided by the time elapsed (t).

v = d/t

t = d/v = 120 mi/(60 mi/h) = 2.0 h

It takes Kevin 2.0 hours to get to the concert.

Answer 2

It takes him 2 Hours to reach the concert.

Explanation:

Given the car can travel 400 miles with a full tank of gas.

It used 30% of the full tank of the gas to get to the concert. Which means it travelled
`400*((30)/(100))`=120 miles.

Also given that kevin travels at 60 miles per hour

That means it takes him one hour to travel 60 miles.

Now to travel 120 miles it takes him 2hours .
