For 1st ,
Let distance travelled be x
Given,
Speed=30km/hr
Time=distance÷speed
Time=x÷30
For 2nd,
Distance will be the same
That is
Distance=x
Speed=40km/hr
Time=x÷40
We know that,
Average speed=total distance÷total time

Sorry. Bt it's incomplete
Why tell me
The answer will be 37 whole 2 upon7
Tell me again
From starting
Average speed =total distance/total time
Total distance=2x ,total time=7x/120
And so u will get 37whole 2 upon 7 km/hr as ur answer
