0.75 is the approximate answer

Answer 2

0.75 gallons of fuel will the car need to travel 30 km.

Explanation:

As given

A car can travel 25 miles per gallon.

As given

1 mile = 1.6 km

Now convert 25 miles into km .

25 miles = 25 × 1.6 km

= 40 km

i.e A car can travel 40 km per gallon.

40 km = 1 gallons.

`1\ km = (1)/(40)\ gallons`

`1\ km = 0.025\ gallons`

Now find out gallons of fuel will the car need to travel 30 km.

Than

gallons of fuel will the car need to travel 30 km = 30 × 0.025

= 0.75 gallons

Therefore 0.75 gallons of fuel will the car need to travel 30 km.
