Answer:

Step-by-step explanation:

Set up a proportion.

3/25 = x / 20 Notice that both times are in the denominators. Be sure you always set up a proportion that way. Like units in the denominator. Like units in the numerator.

Cross multiply

3 * 20 = 25 * x Combine

60 = 25x Divide by 25

60/25 = x

x = 2.4 miles in 20 minutes.
