1.	A Train 125 M Long Passes A Man, Running At 5 Km/hr. In The Same Direction In Which The Train Is Going, In 10 Seconds. The Speed Of The Train Is?
Answer» Let the speed of the train be x km/hr. Given, Speed of the man = 5 km/hr. SINCE both the train and man are moving in the same direction so the speed of the train (relative to man) would be (x-5) km/hr. Length of the train = 125 m = 125/1000 km = 18 km Time taken to cross the man = 10 SEC = 10/3600 hrs. = 1/360 hrs. So speed =distance/time. => x-5 =360/ 8. => 8X - 40 = 360. => 8x = 400. => x = 50 km/hr. Let the speed of the train be x km/hr. Given, Speed of the man = 5 km/hr. Since both the train and man are moving in the same direction so the speed of the train (relative to man) would be (x-5) km/hr. Length of the train = 125 m = 125/1000 km = 18 km Time taken to cross the man = 10 sec = 10/3600 hrs. = 1/360 hrs. So speed =distance/time. => x-5 =360/ 8. => 8x - 40 = 360. => 8x = 400. => x = 50 km/hr.

Answer»

Let the speed of the train be x km/hr.

Given, Speed of the man = 5 km/hr.

SINCE both the train and man are moving in the same direction so the speed of the train (relative to man) would be (x-5) km/hr.

Length of the train = 125 m = 125/1000 km = 18 km

Time taken to cross the man = 10 SEC = 10/3600 hrs. = 1/360 hrs.

So speed =distance/time.

=> x-5 =360/ 8.

=> 8X - 40 = 360.

=> 8x = 400.

=> x = 50 km/hr.
