Atrain 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. show your work. identify if each of the measurements are a scalar or vector quantity.
it needs work not just a simple answer i'm confused on it and i would like to know how to break it down

 im not sure about most of this but ill try to help

so there are three formulas you need to know first: the formula for rate distance and time.

to find distance:
distance = rate * time

to find time:
time = distance / rate

and to find rate (which is what we need)
rate = distance / time

now we just use our formula and plug in the numbers

rate = distance * time

rate = 160 / 2 = 80

so our rate is 80. thats all i know i have no idea about the rest but i always use these messurments. im sure you can google most of it to get other formulas and calculators though. sorry i couldnt help much! good luck :D
