What is average speed?

Average speed is calculated by dividing the total distance by the total amount of time.

Average speed = Total distance travelled / Total time taken

The given values are:

Average speed (v) = 45 miles/hour

Total time taken = 90 miles

By using the formula of average speed:

Average speed = Total distance travelled / Total time taken

v = d/t

45 miles/hour = d * 90 miles

d = [tex]\frac{90}{45}[/tex]

d = 2 Hours

Therefore,

The total distance travelled by car is  2 hours.
