Answer:
43.47 km/h
Step-by-step explanation:
Time required to cover 60 km at 40km/h= Distance/Speed
=60/40=3/2h
Time required to cover next 40 km at 50km/h= Distance/Speed
=40/50=4/5h
Total time= 3/2+4/5=1.5+0.8=2.3hours
Total distance= 60+40=100
Average Speed= (Total distance)/(Total time)
=100/2.3=43.47 km/h
