Answer by haileytucki(390)   (Show Source):
You can put this solution on YOUR website! Rate is distance (given in units such as miles, feet, kilometers, meters, etc.) divided by time (hours, minutes, seconds, etc.). Rate can always be written as a fraction that has distance units in the numerator and time units in the denominator, e.g., 25 miles/1 hour.
If it travels 3 miles in 20 minutes, then it travels 6 miles in 40 mintues.
Now, you still have 5 minutes left over, so:
R=D/T
(3)/(20)
The approximate value of (3)/(20) is 0.15.
0.15
Now. you need to figure out for 45 minutes so:
0.15*45
Multiply 0.15 by 45 to get 6.75.
6.75
You can easily check this by simply multipying the original:
0.15*20
Multiply 0.15 by 20 to get 3.
3 miles
Your answer, as noted above = 6.75 miles traveled
