Question

how can you find the number of inches in one mile

Answer 1

You convert it to feet. There are 5,280 feet in a mile. Then convert it to inches. 5,280 feet multiplied by 12 (since there are 12 inches in a foot) is 63,360.

So... 1 mile= 5,280 feet
         5,280 feet= 63,360 inches
         and so
         1 mile= 63,360 inches
