Lubov Fominskaja [6]

<u>Answer:</u>

First car: 35 gallons

Second car: 15 gallons

<u>Step-by-step explanation:</u>

Assuming $x$ to be the gas consumed by 1st car and $50 - x$ to be the gas consumed by 2nd car.

We know that:

Distance traveled = fuel efficiency × gas consumed

$20x+35(50-x)=1225$

$20x+1750-35x=1225$

$35x-20x=1750-1225$

$15x=525$

$x=35$

So $50 - x = 50-35=15$

Therefore, first car consumed 35 gallons while second car consumed 15 gallons.
