Greyson rides his bike at a constant rate. In 30 minutes, Greyson can bike 7 miles. How far would you expect Greyson to ride in 105 minutes--I already got some of it done, 7 / 30 = 4 with a remainder so then 30 - 28 = 2. ALSO ( extra thing ) He can ride 21 miles in 90 minutes. Please help and thank you!
