Truck coverd 25 km with velocity 200m/s
Then Truck coverd 25 km with velocity of v
If its average speed = 100 m/s
Then we know av = v-u / 2= 100m/s
So now v-200=200m/s
So v= 400m/s
Then Truck coverd 25 km with velocity of v
If its average speed = 100 m/s
Then we know av = v-u / 2= 100m/s
So now v-200=200m/s
So v= 400m/s
