The formula d = 52t + 65t can be used to find the distance, d , between two cars after traveling t hours in opposite directions. After how many hours will the distance between the two cars be 234 miles?

1 answer

We can begin by substituting d = 234 into the formula:

234 = 52t + 65t

Simplifying, we get:

234 = 117t

Dividing both sides by 117, we get:

t = 2

Therefore, after 2 hours of driving in opposite directions, the distance between the two cars will be 234 miles.
