Find whether your brother is correct or not.

Answer to Problem 22CB
Brother is not right.
Explanation of Solution
Given :
Your gas tank holds 13.5 gallons of gas.Your fuel gauge shows that your tank is one quarter full.Your car gets an average of 25 miles per gallon.The GPS shows that you are 85 miles from your destination.Your brother says you will make it.
Calculation:
Given:
Capacity of gas tank = 13.5 gallons
Fuel in gas tank =
Speed of car = 25 miles per gallon
Distance to cover = 85 miles
So, fuel required to cover the distance =
And fuel in the car is 3.375 gallons , which is less than the required fuel of 3.4 gallons to make it to the destination.
So, the brother is not right . You will not make it to the destination in 3.375 gallons of fuel.
