Question 491602: Two cars are 525 miles apart. They start at the same time and travel toward each other. One travels at a rate of 55mph and the other at a rate of 50mph. In how many hours will they meet?
Answer by oberobic(2304)   (Show Source):
You can put this solution on YOUR website! The standard distance equation is d=rt, where d=distance, r=rate, t=time.
d = 525
The cars are approaching each other, so they are closing the gap at the sum of their rates:
r = 50+55 = 105
.
525 = 105*t
So,
t = 5
.
Checking.
.
distance traveled at 50 mph = 50*5 = 250 miles
distance traveled at 55 mpg = 55*5 = 275 miles
total distance traveled = 525 miles.
.
So, they will meet in 5 hours.
.
Done.
