Use the following table of a school bus during morning pickups to calculate its average speed between 2.8 km and 4.2 km.

55 km/h

50 km/h

42 km/h

52 km/h

42.42 km/h

Explanation:

We are required to calculate the average speed between 2.8 km and 4.2 km.

We will need to calculate the average rate of distance between 2.8 km and 4.2 km.

We will divide the distance change by change in time.

Average speed =

Distance change = 4.2 km - 2.8 km

                            = 1.4 km

Change in time = 0.084 h - 0.051 h

                          = 0.033 h

Therefore;

Average speed = 1.4 km ÷ 0.033 h

                          = 42.42 km/h

Therefore, the average speed between 2.8 km and 4.2 km is 42.42 km/h

truck y has a greater velocity than truck x.
