Question

Two cars leave an​ intersection, one traveling west and the other south. After some​ time, the slower car is 7 mi nearer to the intersection than the faster car. At that​ time, the two cars are 13 mi apart. How far did each car​ travel?

Answer 1

Explanation:

let x and y be the distances of each car from the intersection after sometime.

let x<y

then y-x=7

and y+x=13

add 2y=20

y=10

x=13-10=3

slower car travels 3 miles and faster car travels 10 miles
