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?
1.0.5
2.2.0
3.3.6
4.4.0
Substitute 234 for d in the formula:
234 = 52t + 65t
Combine like terms:
234 = 117t
Divide both sides by 117:
t = 2
After 2 hours, the distance between the two cars will be 234 miles. Answer: \boxed{2.0}.
