1. Answer:

   Let train A be travelling at 40 kmph and train B at 50 kmph

   So train A started at 9 am and train B started at 10 am (given in the question),

   By the time train B started, train A already reached a distance of 40 km, lets make a flow chart…..

   Train- Time -Travel time- Distance travelled

   Train A – 10 am – 1 hr – 40 km

   Train B – 10 am – 0 hr- 0 km

   Train A – 11 am – 2 hrs – 80 km

   Train B – 11 am – 1 hr – 50 km

   Train A – 12 pm – 3 hrs – 120 km

   Train B – 12 pm – 2 hrs – 100 km

   Train A – 1 pm – 4 hrs – 160 km

   Train B – 1 pm – 3 hrs – 150 km

   Train A – 2 pm – 5 hrs – 200 km

   Train B – 2 pm – 4 hrs – 200 km

   So at 2 pm, both the trains meet after travelling 200 km….

2. Step-by-step explanation:

   Assuming the train did not stop anywhere in between.

   Time taken by the train= 22:30hrs – 9:40hr

   = 22 1/2hrs –9 2/3 hr

   = (45/2 –29/3)hr

   = (135–58)/6 hr

   = 77/6 hr

   Now, D= s×t

   =62km/hr × 77/6 hr

   = 4774km/6

   = 795.66km
