2/4 mile = 1/2 mile when 2/4 is reduced. 1/2 = 0.5 miles in decimal form.

1/10 = 0.1

0.5 miles        1 mile

0.1 hours         x hours

Solution

Cross multiply

x* 0.5 = 0.1 * 1                        Combine

0.5 x = 0.1                              Divide by 0.5

x = 0.1/0.5

x = 0.2                                   hours.
