Answer 1

Answer:

Hola...

Explanation:

Average Speed = Total Distance / Total Time Taken

Total Distance = 10 + 10 ( He again takes the path )

= 20 km

= 20000 m

Time1 = Distance / Time

= 10 / 20

= 1 / 2 hrs

= 30 minutes

Time2 = 10 / 30

= 1 / 3 hrs

= 20 minutes

Total Time = 30 + 20

= 50 minutes

= 50 × 60 seconds

Average Speed = 20000 / 50 × 60

= 200 / 30

= 20 / 3 m/s

Average Speed = 20/3 m/s

Hope This Helps You!!!

Have A Great Day Ahead!!!
