Answer to Problem 18CR
The distance travelled at 50 mi/h = 75mi
The distance travelled at 55 mi/h = 110mi
Explanation of Solution
Given:
Total distance = 185mi.
Speeds = 50 mi/h and 55mi/h
Total time = 3h 30minutes
Calculation:
Let the distance travelled at 50 mi/h = x
The distance travelled at 55 mi/h = 185 - x
Therefore,
Hence, the distance travelled at 50 mi/h = 75mi
The distance travelled at 55 mi/h = 110mi
