------
For each of these rate-distance combinations
time = distance/rate
Questions:
1. What is the driving time traveling 29.1 miles @ 75 mph, 50 mph, and 12 mph?
at 75 mph:: time = 29.1/75 = 0.3880 hrs
= 0.3880*60
= 23.28 minutes
= 23+0.28*60
= 23 min 16.8 seconds
------------------------
Do the same for 50 mph and 12 mph
----------------------------
The following problems require the same procedure.
