A train leaves the station heading west on the tracks. It takes the train 8 seconds to reach 80 miles per hour. It completes the entire 160 mile trip in two hours. Calculate the train's average speed and velocity over the two hour trip
------------
Speed is a scalar, velocity is a vector.
The number is the same:
160 miles/2 hours = 80 mph
--------------------------
0 to 80 in 8 seconds is a lot of acceleration for a train.
