Question 1014045: In the morning, Maria drove to a business appointment at 70 mph. Her average speed on the return trip in the afternoon was 60 mph. The return trip took 1/6
hr longer because of heavy traffic. How far did she travel to the appointment? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Since rate times time equals distance...we can call the time on the first trip t...the return trip would take t + 1/6...we can write
70t = 60(t + 1/6)
70t = 60t + 10
10t = 10
t = 1 hour
Therefore the trip was 70 miles long, each way.
