<PRE><B>Question 507622</B>
a bus traveled on level road 4 hours at average speed 20 miles per hour faster
distance = r*t = 20*4 = 80 miles
----------------------------------------

than it traveled on a winding road: The time spent on the winding road was 4 hours find the average speed on level road if the entire trip was 376 miles
distance = t*r = 4r miles
----
Equation:
distance + distance = 376
80 + 4r = 376
4r = 296
rate = 72 mph (rate on the level road)
==========================================
