So, the total time taken by Jack = 



Also, Sandy averages 20 miles per hour in both directions,
So, the total time taken by Sandy = 




∵ 0.133D > 0.10D
Hence, Sandy will finish the race first.

Answer:

Step-by-step explanation:
Given
Rent per day = $49
Addition = 5 cents per mile
Required
Determine the rent for a day and m miles
First, we need to generate a formula from the given parameters;
