How many miles did Abe ride?

Question

Amil rode 15 miles in 55 minutes. Abe rode for 77 minutes. Their rates were proportional.

Answer 1

We don't know how many miles Abe rode; this is our unknown, which we can call x. Since the rates are proportional, we can set up the following:

 

15/55 = x/77

 

Can you now solve this for x, Millie?
