Answer 2

Answer: The answer is 13 km/h

Step-by-step explanation:

first using the given info calculate the time taken in each case by applying the formula T = D/S,

T1 = 96/16 = 6 km/h

T2= 124/31 = 4km/h

T3 = 105/7 = 15 km/h

Add the answer derived in each case, now you have got the Total time taken which is 25 hrs.

Do the same with the distance ( 96 + 124 + 105 = 325 )

Apply the formula of Avg speed: Total distance/total time taken

Avg speed = 325/25

= 13km/h
