Question

The distance between two stations A and B is 300 km
A train leaves the station with a speed of 40 km/h. At
the same time another train departs from the station B
with a speed of 50 km/h. How much time will these
two trains take to cross each other?
(a) 3 h 40 min
(b) 3 h 20 min
(C) 2 h 20 min
(d) 3 h 45 min​

Answer 1

Answer:

b) 3 h 20 mins.

Step-by-step explanation:

TOTAL KM = 300 km.

Speed of train 1 = s¹ = 40km/h.

Speed of train 2 = s² = 50km/h.

Time taken by s¹= 300/40 = 7.5 that is 7 hrs and 30 mins.

Time taken by s²= 300/50 = 6 that is 6hrs.

half of time taken by s¹ = 3 h 15m

half of time taken by s² = 3 h.

Hence approximately they meet at 3h 20 mins.
