Two Stations A And B Are 200 Km Apart On A Straight Track. One Train

1.	Two Stations A And B Are 200 Km Apart On A Straight Track. One Train Starts From A At 7 A.m. And Travels Towards B At 20 Kmph. Another Train Starts From B At 8 A.m. And Travels Towards A At A Speed Of 25 Kmph. At What Time Will They Meet?
Answer» <P>Assume both trains meet after 'p' hours after 7 a.m. Distance covered by train starting from A in 'p' hours = 20p km Distance covered by train starting from B in (p-1) hours = 25(p-1) Total distance = 200 => 20X + 25(x-1) = 200 => 45X = 225 => p= 5 Means, they meet after 5 hours after 7 am, IE, they meet at 12 p.m. Assume both trains meet after 'p' hours after 7 a.m. Distance covered by train starting from A in 'p' hours = 20p km Distance covered by train starting from B in (p-1) hours = 25(p-1) Total distance = 200 => 20x + 25(x-1) = 200 => 45x = 225 => p= 5 Means, they meet after 5 hours after 7 am, ie, they meet at 12 p.m.

<P>Assume both trains meet after 'p' hours after 7 a.m.

Distance covered by train starting from A in 'p' hours = 20p km

Distance covered by train starting from B in (p-1) hours = 25(p-1)

Total distance = 200

=> 20X + 25(x-1) = 200

=> 45X = 225

=> p= 5

Means, they meet after 5 hours after 7 am, IE, they meet at 12 p.m.
