Question

The first car has a fuel efficiency of 35 miles per gallon of gas and the second has a fuel efficiency of 15 miles per gallon of gas. During one particular week, the two cars went a combined total of 1350 miles, for a total gas consumption of 50 gallons. How many gallons were consumed by each of the two cars that week?

Answer 1

Answer:30 gallons by first car

Explanation:

Given

First car consumption is 35 miles per gallon

Second car consumption is 15 miles per hour

Total Gas consumption is 50 gallons

Total distance traveled 1350 miles

Let x be the fuel consumed by first car therefore second consumes 50-x

`35* x+15* \left ( 50-x\right )=1350`

x=30 gallons

first car consumes 30 gallons and second consumes 20 Gallons
