For finding average speed of a vehicle covering equal distances in different time intervals, we prefer to use (a) A.M.         (b) G.M.          (c) H.M.         (d) Median

If the distance of 200 m is covered in 20 s, then the speed is

A body of mass (m) moving along a straight line covers half the distance with a speed of 2 m/s. The remaining half of the distance is covered in two equal tiem intervals with a speed of 3 ms^(-1) and 5 ms^(-2) respectively. The average speed of the particle for the entire journey is .

A particle moving in a straight line covers half the distance with speed of 3 m//s . The other half of the distance is covered in two equal time intervals with speed of 4.5 m//s and 7.5 m//s respectively. The average speed of the particle during this motion is :

A farmer moves along a square field of side 10 m in one hour. Write the following steps in sequential order to find his average speed. (A) . Find th total distance (s) covered by the farmer. (B) Note down the total time (t) required to cover the total distance. (C) Use the formula , average speed = ("total distance")/("total time") (D) Substiute the values of s and t to determine the average speed.

At which time number of minutes elapsed since midnight is nine times the number of minutes before noon? (a) 8.30 a.m. (b) 6.56 a.m. (c) 9.46 a.m. (d) 10.48 a.m.

In a 100 m race, A covers the whole distance in 36 seconds and B in 45 seconds. In this race, A beats B by (a) 20 m (b) 25 m (c) 22.5 m (d) 9 m

A particle moves on a straight line in such way that it covers 1st half distance with speed 3m // s and no half distance in 2 equal time intervals with speeds 4.5 m/s and 7.5 m // s respectively. Find average speed of the particle.
