Atrain leaves the station heading south on the tracks. it takes 5 seconds to reach 50 miles per hour. it completes the entire 100 mile trip in 2 hours. calculate the trains average speed and velocity over the two hour trip. show your work. identify each of the measurements are a ascalr or vector.

Well, in order to figure out the answer is to divide until you figure out how many miles they went per second. If it takes 5 seconds to reach 50 miles per hour it took 10 seconds per every 10 miles meaning each mile took 1 second. (Not actually possible but the answer) So, If it finished a 100 mile trip in 2 hours it took an hour for 50 miles. If it took 1 hour for 50 miles divide 60/50 which gets you 1.2 so it took 1.2 miles per minute meaning the car went 120 miles per hour I believe. I hope this helps :)
