Question 133573: Paul and Susan are 725 miles apart and headed straight toward each other. If Paul is traveling at 75 mph and Susan is traveling at 70 mph, how many hours will it be before the two cars are side-by-side? Answer by josmiceli(19441) (Show Source):
You can put this solution on YOUR website! The variable that is the same for both of them is time. If I
start my stopwatch when they are 725 mi apart and stop it
when they meet, they have both travelled for the same amount
of time.
Let = distance that Paul travels will be the distance that Susan travels
For Paul: hrs
For Susan: hrs
Since their times are equal,
Multiply both sides by
Now find hrs
They will meet in 5 hrs
check:
OK
