PLEASE HELP!!
Suppose an ostrich runs 1.5 km at a speed of 58 km/h and then runs another 1.5 km at a speed of 29 km/h. What is the ostrich’s average speed during the 3.0 km run? (Hint: find the total time first by finding the time of each 1.5 km segment)

Answer :

Answer: 38.46 km/h

Distance 1= 1.5km
Distance 2= 1.5km
Speed 1= 58km/h
Speed2= 29km/h
S= Distance/time= 58=1.5/t
t=1.5/58=0.026
t=1.5/29=0.052
Average Speed= Total Distance/Total time= 3/0.026+0.052= 38.46 km/h
