Problema Solution
Two cars leave towns 600 kilometers apart at the same time and travel toward each other. One car's rate is 16 kilometers per hour more than the other's. If they meet in 4 hours, what is the rate of the faster car?
Answer provided by our tutors
First, find out how many kilometers in an hour:
600/4 = 150
Then, figure out the speed per hour:
x + (x + 16) = 150
Then solve for x
2x + 16 = 150
2x = 134
x = 67
So, one car is going 67 kph, the other is going 84 kph
