Answer:
48 km/hr
Step-by-step explanation:
since the distance is constant, we can find
average speed =\frac{total distance}{total time} \\
total distance = 2* speed*time (going from H to B and coming back)= 2*60*30=3600 km
total time= 30 hours (H to B) + (1800km/40km per hour)(B to H)= 30 + 45= 75 kmph
hence average speed= 3600/75= 48kmph
