Question

Lin rode a bike 20 miles in 120 minutes at the constant speed. how long did it take her to ride 6 miles​

Answer 1

It would take Lin 36 minutes to ride 6 miles. To answer this you must divide 120 by 20. You'll get the answer 6. This is your unit rate. You then take the unit rate, 6, and multiply it by how many miles she rode. In this case, 6*6. Or if you prefer an equation: (120÷20)*6=36min.
