Calculate their speed between points A and B. Include the units. What was their average speed for this ride? Include the units.​

Speed between point A and B

= Total Distance/Total time

= 30/3

= 10 km/h

Average speed for this ride

Average speed = Total distance travelled/time taken

= 50/6

= 8.3 km/h
