Answer:
The horse's average speed is 0.527 m/s
Step-by-step explanation:
step one:
In this problem, we are not asked explicitly what to solve for, but given the following data we can solve for the average speed
step two:
We know that average speed = total distance/total time taken
total distance= 15m+20+4m= 39m
total time= 74 seconds
step three:
average speed= 39/74
average speed= 0.527 m/s
The horse's average speed is 0.527 m/s
