Post A and Post B are 120 meters apart. Post B and Post C are 300 meters apart. Ben cycled from Post A to Post B in 15 seconds. Then he cycled from Post B to Post C in 55 seconds. Find Ben's average speed for the distance from post A to Post C.
The formula for Velocity(speed) is delta x/ delta t or a change in distance(magnitude) over a change in time. The formula goes as follows X^2 -X^1 / T^2-T^1 so 300-120/55-15 --> 180/40 --> 4.5 m/s(avg. speed).
