Grady rides his bike 60% faster than his little brother Noah. If Grady rides 15 miles further than Noah in two hours, how fast in miles per hour does Noah ride?

Given: G = 1.6 N

In ONE hour Grady rides 7.5 miles MORE than Noah

G = N + 7.5 sub in the red equation

1.6 N = N + 7.5

** N = 12.5 m/hr**
