Case 1
Speed = 50km/h
Distance= 150km
Time= 150/50hrs =3hrs
Case 2
Speed=75km/hr
Distance=150km
Time=150/75hrs =2hrs
Now,
Average speed= Total distance/Total time
=300/5 km/hr = 60km/hr
Speed = 50km/h
Distance= 150km
Time= 150/50hrs =3hrs
Case 2
Speed=75km/hr
Distance=150km
Time=150/75hrs =2hrs
Now,
Average speed= Total distance/Total time
=300/5 km/hr = 60km/hr
