Question 534141: If a car is traveling 45 miles per hour and it has to go 4.5 miles, how many minutes does it take for the car to arrive at its destination? Answer by oberobic(2304) (Show Source):
You can put this solution on YOUR website! 45 mi/hr / 60 min/hr = 3/4 mi/min
.
4.5 miles / (3/4 mile/min) = 4.5 * 4/3
.
Recall that dividing by a fraction can be calculated by multiplying with the reciprocal of the fraction.
.
4.5 * 4/3 = 18/3 = 6
.
I will take 6 minutes to travel 4.5 miles at a steady speed of 45 miles/hr.
.
To check we can consider the relationship to 6 minutes to 1 hr.
6 minutes is 1/10 (one tenth) of an hour: 6/60 = 1/10.
So it will take 1/10 hr * 45 mph = 4.5 miles
.
Done.
