Question

Two cars are traveling in the same direction the first car is going 40 miles per hour and the second car is going 55 miles per hour the first car left 3 hours before the second car which equation could you use to find how many hours it will take for the second car to catch up

Answer 1

I hope this helps you




distance=speed×time



first cars time t




second cars time t+3




distance=55.t



distance=40. (t+3)



55t=40t+120



15t=120


t=8



t+3=11
