Thank you for the opportunity to help you with your question!

 First time 20 hours at a speed of 40 km/hr

Second time 2 hours at 60 km/h

First Distance= 40 x 20

=800 Km

second distance= 2 x 60

=120 km

Total Distance 120 + 800=920 Km

Total Time = 22 Hours

Average Velocity = Distance/ time


= 41.81818  Km/hr

Converting it to  M/Seconds

Total distance is 920 Km = 920000m

Total Time  22 hours = 79200  s

velocity = 11.61616  m/s
