Answer / guest
Given total distance already ie equal to 120km
T1 = (120/2) / 60 = 1 hr
T2 = (120/2) / 40 = 1.5 hr
Total time T = 2.5 hr
Average speed = 120 / 2.5
= 48 kmph

Answer / neel
Ans=24
avg veocity=Total Distance travelled/Total Time Taken
T1(Time taken to go)= 120/60=2
T2(Time Taken to return)=120/40=3
Total Distance=120+120=240
Total Time=2+3=5
So, Avg speed=total distn/time=240/5=48kmph

Answer / chetankumar
60*x=120
40*y=120
x=2 hrs
y=3 hrs
total distance over total time
total time is 5 hours
120+120=240 total distance
240/5
=48 kmph
