Question

if two train running at different speed (a>b) reach each other in r hrs. while running in same direction and in q hrs while running in different direction,distance being the same.then what is the relation between the speed of the train​

Answer 1

Answer:

72sec

Step-by-step explanation:

Total distance to be covered = 400 + 360 = 760 m = 760/1000 km.

Relative Speed = 92 - 54 km/hr = 38 km/hr

∴ Time taken by train to cross = Distance/ Speed = (760/1000)/38 km/hr

= 1/50 × (60 × 60) sec = 72 sec.
