SOLUTION:
If you drive at 55 mi/h for 110 miles, this means you drovefor 110 / 55 = 2 hours
Your total driving time is 4 hours and 15 minutes which meansthat you drove 2 and 15 minutes at the rate of 35 mi/h
2 hours and 15 minutes = 2×60 + 15 = 135minutes
35 miles / 60 minutes × ( 135 minutes) = 78.75miles
So total miles driven is 78.75 + 110 =188.75 miles
