Answer:

1.5 miles

Step-by-step explanation:

set up a proportion:

0.5           x

--------   = ---------

20            60

0.5(60) = 20x

30=20x

(divide by 20 on both sides)

x= 1.5 miles

1.5 miles because 3 times 20 mins is 60 mins which is one hour and there’s .5 miles every 20 mins so 3x.5 is 1.5
