Hint:Here for such conversion you need to know the details or conversion rate from one unit to another, both units given in the question are for measuring length and length units are very standard and used according to the amount we have to measure. Here we know the conversion value and can solve further.
Formulae Used:
1mile=5280feets

Complete step by step solution:
The given conversion is from “15” miles to feet, on solving we get:
We know that:
1mile=5280feets
By using the above conversion we can convert our given question in the required unit we want, on solving we get:
15miles=15×5280feets=79200feets
This is our required conversion we are looking for, here the value of feet is very large and accordingly we can use scientific notation to write the value as follows:
79200feets=7.92×104feets

Additional Information: Feet and miles is used as measuring length units, feet is here the international standard in measuring length. Feet are used as standard. While conversion of smaller unit to bigger unit you always have to divide, and at the same time while converting bigger unit to smaller you have to multiply.

Note: Unit conversion should be done according to the proper information of conversion from one unit to another, when you are dealing with length measuring then only you need meter and centimeter or millimeter and kilometer. According to the amount of length you are measuring you have to deal with such units higher the length higher the measuring unit.
