A horse canters away from its trainer in a straight line, moving 37 m away in 9.1 s. It then turns abruptly and gallops halfway
back in 1.8 s . Calculate its average speed for the entire trip.

Answer:
Average velocity = 1.69 m/s
Average speed = 5.09 m/s
Explanation:
Given that
Horse cover 37 m in 9.1 sec and 18.5 m in 1.8 sec.
As we know that
Average velocity = Displacement / Total time
Average speed = Total distance / Total time
Average velocity:
Average velocity = Displacement / Total time
Total displacement = 37 - 18.5 = 18.5 m
Total time = 9.1 + 1.8 =10.9 s
Average velocity = Displacement / Total time
Average velocity = 18.5 / 10.9
Average velocity = 1.69 m/s
Average speed:
Average speed = Total distance/ Total time
Total distance = 37 + 18.5 = 55.5 m
Total time = 9.1 + 1.8 =10.9 s
Average speed = Total distance/ Total time
Average speed = 55.5 / 10.9
Average speed = 5.09 m/s
