Question

A man covers a distance with speed V1 and V2 for two equal time period . find average speed​

Answer 1

Answer:

Average speed = V1 + V2 / t + t = V1 + V2 / 2 t

Answer 2

Answer:

Initial speed=v1

let time be t1

therefore , distance=v1×t1

final speed=v2

let time be t2

therefore, distance=v2×t2

average speed=(v1t1+v2t2)(t1+t2)
