Answer 2

Average speed of the car is equal to
`40 miles/hour.`

Step-by-step explanation:

In the given question it is given that Bernie drove a distance of
`60 miles`. The total time taken for the drive is
`1.5 hours.`

distance
`d=60 miles`

time
`t= 1.5 hours`

average speed
`v_av= (total \ distance)/(total \ time)`

`=d/t = 60/1.5= 40 miles/hour`

Average speed is the quantity used to define the motion of an object during a specific time interval. SI unit of speed is m/s. To find average speed of a body from the position-time graph we have to calculate the slope of the graph corresponding to the given time interval.
