1.	a train cover the first 50km of its journy in 30 min the, next 20km in another 10 min and last 80 in 20 min . calculate the average speed of the train.
Answer» total DISTANCE = 50+20+80=100km = 100000mtotal TIME= 30+10+20=60min=3600secsaverage SPEED of the train =total distance/total time =100000/3600 =27.77m/shope this is correct & HELPS
