A horse rider covers half the distance with `5m/s` speed.The remaining part of the distance was travelled with speed `10m/s` for half the time and with speed `15m/s` for other half of the time.The mean speed of the rider averaged over the whole time of motion is `(x)/(7)m/s`.The value of `x` is

09A body moving in a straight line covers half the distance with a speed V the remaining part of the distance was covered with a speed V for half the time and with a speed V for the other half of the time.What is the average speed of the body?

A point traversed half the distance with a velocity v_0 . The remaining part of the distance was covered with velocity v_1 for half the time, and with velocity v_2 for the other half of the time. Find the mean velocity of the point averaged over the whole time of motion.

A man traversed half the distance with a velocity v_(0) . The remaining part of the distance was covered with velocity V^(1) . For half the time and with velocity v_(2) for the other half of the time . Find the average speed of the man over the whole time of motion. .

A body travelling along a straight line traversed one third of the total distance with a velocity 4m/s. The remaining part of the distance was covered with a velocity 1 m/s for half the time and with velocity 3 m/s for the other half of time. The mean velocity averaged over the whole time of motion is :

A particle travels along a straight line. It covers halg the distance with a speed (v). The remaining part of the distance was covere with speed v_(1) for half the time and with speed v_(2) for the other half the time . Find the average speed of the particle over the entire motion.

A particle travels half the distance of a straight journey with a speed 5m/s .The remaining part of the distance is covered with speed 6m/s for half the remaining time,and with speed 4m/s for the other half of the remaining time.The average speed of the particle is

A particle travels half the distance of a straight journey with a speed 5 m/s. The remaining part of the distance is covered with speed 6 m/s for half the remaining time, and with speed 4 m/s for the other half of the remaining time. The average speed of the particle is

A body travelling along a straight line traversed one-third of the total distance with a velocity v_1 . The remaining part of the distance was covered with a velocity v_2 for half the time and with velocity v_3 for the other half of time. The mean velocity averaged over the whole time of motion

A cae is travelling along a straight line. It covers one-half of the total, distance with a velocity 10 km//h . The remaining part of the distance was covered with velocity 12 ms^(-1) . For half the time and with velocity 16 ms^(-1) for the other half the tiem. Find the average speed over the whole time of motion.
