John walks 3/5 of a mile every 1/4 hour. If john 3 1/2 hours, at the same rate, how much distance will he cover?

Answer 1

There are several ways to approach this problem; here is one way.

(3/5)/(1/4) = John's rate in miles per hour = 12/5 mph

3 1/2 hours = 7/2 hrs

Distance = rate * time= (12/5) * (7/2) = 42/5 = 8 2/5 miles
