Answer:

driving car is more speed than the speed limit because avg speed is that car is 62.22 mi/hr

Step-by-step explanation:

Given data

distance = 28 mi

time = 27 min

car speed limit = 60​ mi/hr

to find out

conclude that the driver exceeded the speed​ limit

solution

we calculate here avg speed from mean value theorem i.e

avg speed = (total distance) / (total time)

avg speed = (28 - 0) / ((27/60) - 0 )

avg speed = 62.22 mi/hr

so we can say that that driving car is more speed than the speed limit because avg speed is that car is 62.22 mi/hr
