PLEASE HELP! 3ND TIME I ASKED THIS!!!

Emma is riding on a train. The train is moving at 50 m/s. Emma walks down the aisle at 1 m/s relative to the train in the same direction the train is moving. what is her relative velocity? Also, I know the equation for relative velocity is "t = Δx ÷ v" but how would that fit into this type of equation?? Please show you're work!

Relative to the ground Emma's velocity is 50 m/s + 1 m/s =

Answer: 51 m/s

We don't use that other equation.

Problem:

Emma Rides on a train/ Moving ==========> 50 m / s

Emma walks down the aisle =============> 1 m / s

Emma's Relative Velocity ==========> 51 m / s



Solution:

Formula: ===========> t = Δx ÷ v

Relative velocity:

Δx = v t → t = Δx / v

t = (50 ms ) / (1 ms ) = 50 m / s + 1 m / s

= 50 m / s + 1 m / s

Answer ================> Emma's Relative Velocity 51 m / s



Hope that helps!!!! : )
