A man walks for some time 't' with velocity(v) due east. Then he walks for same time 't' with velocity (v) due north. The average velocity of the man is:-

A person travels along a straight road for the half time with a velocity V_1 and the next half time with a velocity V_2 . The mean velocity V of the man is

A person travels along a straight road for the half time with a velocity V_1 and the next half time with a velocity V_2 . The mean velocity V of the man is

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 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 man runs along the straight road for half the distance with velocity v_(1) and the remaining half distance with velocity v_(2) . Then the average velocity is given by
