Nina can ride her bike 63,360 feet in 3,400 seconds, and Sophia can ride her bike 10 miles in 1 hour. What is Nina’s rate in miles per hour if there are 5,280 feet in a mile?

Step-by-step explanation:

So first off we want to find out how many miles Nina can ride in 3,600

For this we have to convert 63,360 feet into miles

If there are 5,280 feet in one mile than we need to see how many times 5,280 goes in to 63,360

divide 63,360 by 5,280: you get 12

This means that she can bike 12 miles in 3,600 seconds

3,600 seconds is the same as an hour

Nina can bike 12 miles per hour
