Question

A body moving along a straight covered 1/3 of the distance with speed V1 and 1/3 the remaining distance with speed V2 then find the average speed for the entire journey

Answer:

Average speed = total distance covered /total time taken

let the total distance =3x

time taken to cover first one third (x) = t1 = x/v1

time taken to cover second one third =t2= x/v2

time taken to cover 3rd one third = t3= x/v3
