Question

Two cars leave from the same parking lot, one driving north and the other driving south. The first car is traveling at a speed of 72 mph and the second is traveling at a speed of 68 mph. How long will it take before they are 560 miles apart?

Answer 1

let t = time

you know distance = speed x time

so the distance traveled by car A at time t is 72t

the distance traveled by car B is 68t

it says the sumof their distance is 560 so

72t + 68t = 560

solve for t
