Question: We are 2 pairs of consecutive 2 digit numbers that are factors of the number of feet in a mile. Who are we?

Please help me solve this problem.

Thank you,

 

I don't know. One mile is 5280 feet, and 5280 = 2 2 2 2 2 3 5 11. There are many ways of regrouping these prime factors to get pairs of consecutive 2-digit numbers as factors:

5280 = 10 11 48 = 11 12 40 = 15 16 22 = 32 33 5.

There is no way to tell which two pairs they mean.
