​b) How far can the car be driven on 138 gallons of​ gasoline?

Answer 1

a) 101.125 gallons.

b) 3312 miles.

Explanation:

You know that Jane​'s car will go 420 miles on 17.5 gallons of gasoline in highway driving, therefore:

a) You can calculate the number of gallons it will take to drive 2427 miles from her house to a​ friend's house as following:

`(420miles)/(17.5gallons)=(2427miles)/(x)\\x=101.125gallons`

b) You can calculate the distance the car can be driven on 138 gallons of​ gasoline as shown below:

`(420miles)/(17.5gallons)=(y)/(138gallons)\\y=3312miles`
