Answer:

Step-by-step explanation:
In training for an Olympic bike race, Ped Al Moore trained by riding 216 miles in 12 hours, for an average of 18 miles per hour.
Speed is inversely proportional to the time taken

speed is 18 miles per hour and distance is 216 miles

Let 's' be the speed and 't' be the different time


Replace distance by 216

Assume the number we are looking for in n
we want to know the value of n that makes 1/7 divided by n is 14
Transforming this to an equation:
(1/7) / n = 14
this means that:
1/7 = 14n
1 = 7 x 14n
1 = 98n
n = 1/98
Therefore:
1/7 divided by 1/98 will give us 14
Answer:
The final balance is $5,389.
The total compound interest is $389.
