Question

Speed, Velocity or Acceleration?

A train left the station
heading towards Dallas
at 75 miles per hour
north.

Answer 1

Velocity

Step-by-step explanation:

Speed is how fast something moves.

Velocity is how fast it moves and in what direction it moves in.

Acceleration is the change in how fast it moves. I.e. if it speed up or slows down.

Here we are given the speed of the train (75mph) and the direction (north), therefore it is velocity.

Hope this helped!
