A car completes its journey in a straight line in three equal parts with speeds `v_1,v_2 and v_3` respectively. The average speed `v` is given by :

If a body covers a three equal distances with speeds v_1,v_2 and v_3 then what is the average speed of the body?

A particle moving in a straight line covers half the distance with speed v_(0) . The other half of the distance is covered in two equal time intervals with speed v_(1) and v_(2) , respectively. The average speed of the particle during this motion is

A car complete the first half of its journey with speed v_(1), and the rest half with speed v_(2). The average speed of the car in whole journey:

A car travels along the four sides of a square at speeds v,2v,3v,4v respectively. If u is the average speed of the car in its travel around the square, then which one of the following is correct?

If particle travels n equal distances with speeds v_(1), v_(2),…v_(n) , then the average speed vec v of the particle will be such that .

If particled travels n equal distances with speeds v_(1), v_(2),…v_(n) , then the average speed vec v of the particle will be such that .

A particle moves in a straight line from A to B with speed v_(1) and then from B to A with speed v_(2) . Find the average velocity and average speed.
