Question

Estimate the maximum velocity of the train in kilometers per hour during the time it moves east ( t = 14 min to t = 23 min). 

Answer 1

when an object is moving along x-direction with constant velocity $v$ from time t₁ to t₂.

Then the displacement $\Delta x=v\Delta t$ .

where , $\Delta t$ is the difference in time which is $(23-14)min$ .

After calculating $\Delta x$ we can then estimate the maximum velocity as

$$V=\Delta x/\Delta t$$

Answer:

Hence we can estimate the maximum velocity when a train moves in east direction.
