Answer:
60 km
Step-by-step explanation:
Let the two trains meet at a point C after 'x' hours.
∴ Distance = Speed * Time
(i)
Speed = 20 km/hr and Time = x.
Distance traveled by train starting from station A during x hours:
= 20x km.
(ii)
Speed = 10 km/hr and time = x hours.
Distance traveled by train starting from station B during x hours:
= 10x km
Given:
Total distance between trains = 90 km.
⇒ 20x + 10x = 90
⇒ 30x = 90
⇒ x = 3
Required distance AC = 20x
= 20 * 3
= 60 km.
Therefore, trains meet at 60 km from A.
Hope it helps!
