bob left work and traveled to school at an average speed of 25 mph. if it took bob 35 minutes to reach school, how far is bobs school from his place of work
rate x time = distance 25 x 35/60 = distance (35/60 is 35 minutes out of an hour- 60 minutes) 25/1 x 7/12 = distance (I put the 25 over 1 and reduced 35/60) 175/12 ≈ 14.58 miles
Notice that the time had to be in a fraction of an hour in order to do this.
