A train at a constant 60.0 km/h moves east for 40.0 min, then in a direction 50.0^(@) east of due north for 20.0 min, and then west for 50.0 min. What are the (a) magnitude and (b) angle of its average velocity during this trip?

A train moves with a constant speed of 36 km h^(-1) in the first 10 minutes , with another constant speed of 45km h^(-1) in the bext 10 minnutes and then with an acceleration of 5 ms^(-2) in the last 10 minutes. Calculate the average speed of last 10 minutes . Calculate the average speed of the train for this journey and the total distance travelled.
