I'm having trouble with two physics problems.

- Ashley runs 3.0 km in 4.00 minutes. What is her average velocity? The answer is 45 but I can't figure out how to get it.

- A train moving at 15 km/hr takes 1 minute to come to a stop, find its rate of acceleration, its average velocity and the distance it takes to stop.

Rate of Acceleration

--------------------

15/60 = .25

Average Velocity

----------------

Need help finding this

Distance

--------

15/3.6 = 4.16

4.16 m/s

-------- = .069 m/s^2

60s

Thanks!
