Problema Solution
Rachel runs 3 miles in 25 minutes. At the same rate, how many miles would she run in 20 minutes?
Answer provided by our tutors
since speed = distance/time the rate of Rachel is
v = 3/25 miles per minute
if t = 20 min we need to find the distance d
d/20 = 3/25 multiply both sides by 20
d = 3*20/25
d = 2.4 miles
Rachel will run 2.4 miles in 20 minutes.
