We know Speed =
(Distance )/(time)

Average speed =
(Change in distance )/(change in time)

Average speed is nothing but the slope

Now we find slope from the given graph

The graph starts at (0,0)

The bile reaches 14miles in 1 hour (1, 14)

We got two point (0,0) and (1,14)

Slope =
(y_2 - y_1)/(x_2-x_1)=
(14 - 0)/(1-0)

=
(14)/(1) = 14

So Average speed = 14 mph
