Two cars are traveling in the same direction. The first car is going 40 mph and the second car is going 55 mph. The first car left 3 hours before the second car. What is the equation you need to use to find o it how many hours it will take for the second car to catch up to the first car?
40x=55(x-3) divide both sides by 5 8x=11(x-3) distribute 8x=11x-33 minus 8x both sides 0=3x-33 add 33 both sides 33=3x diide both sides by 3 11=x answer is after 11 hours (440 miles)
