Answer 1

Answer:

b) 37.5 km/hr (PLEASE MARK AS BRAINLIEST)

Explanation:

Speed = Total distance/Total time

Total distance  =  from A to B and back to A

                         = 150km + 150km

                         = 300km

Total time = 3hr + 5hr

                 = 8hrs

Speed = 300/8

= 37.5 km/hr
