Answer:
4 hours
Step-by-step explanation:
First car distance
d = 45h
Second car distance
d = 25h + 80
After how many hours will the two cars be the same distance from the Math City?
Equate both car's distances
45h = 25h + 80
Collect like terms
45h - 25h = 80
20h = 80
Divide both sides by 20
h = 80 / 20
= 4
h = 4 hours
The two cars will be at the same distance from the Math City in 4 hours
