45 minutes = (45 minutes) * [ (1 hour)/(60 minutes) ] = (45/60) hours = 0.75 hours

In summary

45 minutes = 0.75 hours

----------------------------------------------------------------------------------------

Distance = Rate * Time
D = R*T
3 = R*0.75
3/0.75 = R*0.75/0.75
4 = R*1
4 = R
R = 4

His rate or speed is 4 miles per hour

Distance equals rate time so rate equals distance divided by time. Hint: 45 minutes is 3/4 of an hour. So depending on whether you want to express the
rate as miles per minute or miles per hour determines whether you divide by 45 or by 3/4.
