d=rt
d/t=r
distance=5 miles
time = .75 hr
5mi/.75 hr = 20/3 miles/hour ~ 6.66 miles/hour

d = 5 miles
t = 45 min =45/60 hrs
so average speed is = d/t
= 5/(45/60)= 5*60/45 = 60/9 = 20/3 = 6.66 miles/hr

Now,
45 min = 5 miles
60 min = 5*60/45 = 5*4/3 = 5*1.33 = 6.667 miles per hour

5 is to 45 minutes as x is to 60 minutes 5x60/5=x

5 over 45 = x over 60. thus 5x60=300, 300 dvided by 45 = answer.

d = rt
d/t = rt/t
d/t = r This is the formula to be useed
- - - - - - - - - - - - - - - - - - -
d/t = r
5 ÷ 3/4
5/1 x 4/3 = 20/3
20/3 = 6.666666667
6.66 miles per hour rounded to two decimal places.
