ziro4ka [17]

50mph

Step-by-step explanation:

The image of the motion of Paul's derive is attached already.

From the line graph we can obtain a lot of information that will help us unravel the average speed of Paul within the given time frame.

What is average speed?

 Average speed is the rate of change of total distance covered with time taken .

Average speed = \frac{total distance }{time}

To find the total distance covered;

 Distance at time 1 = 75miles

  Distance at time 4 = 225miles

Distance covered between 1 - 4 = 225 - 75 = 150miles

Time taken for the journey = 4 - 1 = 3hrs

Input the values in the equation;

   Average speed = \frac{150}{3} = 50mph
