Question

Let $m$ represent the number of miles. Which algebraic expression represents the number of feet in $m$ miles?

A $5280m$

B $\frac{5280}{m}$

C  $m+5280$

D $5280-m$

Step-by-Step Solution

Answer

Option A $5280m$ represents the correct expression of the number of feet.

Step 1. Conversion of miles to feet.

It is known that there are 5280 feet in one mile.

Step 2. Example of conversion of miles to feet.

5 miles in feet is given by $(5280\times 5)=26400\text{\hspace{0.17em}\hspace{0.17em}feet}$

Step 3. DESCRIPTION OF STEP.

As there are 5280 feet in one mile, so m miles will have $(5280\times m)$ feet.

That is $(5280\times m)$ feet which are given in option A.
