Answer 2

• Total distance = 9km

• Total time taken = ( 7 o'clock - 6 o'clock ) = 1 hour

• Average Speed = Total distance covered / Total time taken

• Average Speed = 9 / 1 = 9 km/h

The average speed in 2nd journey :

• Total time = ( 40 + 5 ) = 45 minutes, Time left to reach golu's house = 60 - 45 = 15 minutes

• Distance = ( 9 - 6 ) = 3km

• Average Speed = 3 / 15 × 60 = 12 km
