Question 772922
On a trip to take your brother to college, you and your parents travel 70 miles per hour on the way there and 55 miles per hour on the way home. The trip home took one hour more than the trip there. The total distance for the round trip was 805 miles. How many hours did it take for the whole trip?
---------------
805 miles RT --> 402.5 miles each way.
---
d = r*t
t = d/r
---
Going, t = 402.5/70 hours
Back, t = 402.5/55 hours
===============
That doesn't fit the data.
The difference is not 1 hour.
