Answered by Ms. Sue
One way to solve this problem is by using a proportion. Cross multiply and solve for x.

20/15 = x/1

15x = 20

x = 20/15

x = 1.333 miles per minute

Are you sure your problem has used the right figures? Typical bike-riding speed is about 15 miles per hour or 1/4 mile per minute.
