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. which equation could yhu solve to find how many hours it will take for the second care to catch up?
40t+120=55t
55t+165=40t
55t+3=40t
40t+3=55t

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
