Acar moves with an average speed of 45 miles/hour. how long does the car take to travel 90 miles?

= 2 hours

Speed is the distance covered by a moving body per unit time.

Thus, speed = distance/time

Therefore; time will be given by distance divided by time

Hence; time =Distance/time

           distance = 90 miles

           speed = 45 miles/hour

Time = 90 miles/45 miles/hour

        = 2 hours

Therefore, a time of two hours is taken by the car to travel 90 miles when moving at a speed of 45 miles/hour.

first one is a: renaming a fraction. second one is c: de-c
