Time Distance and Speed
Two trains, each 100 m long, moving in opposite directions, cross each other in 8 seconds. If one is moving twice as fast the other, then the speed of the faster train is:
A. 30 km/hr B. 45 km/hr
C. 60 km/hr D. 75 km/hr
Read Solution (Total 3)
-
- Ans: C
Let the speed of the slower train be x
and the faster train = 2x
Relative speed = x+2x = 3x
therefore (100+100)/8 = 3x
=> x = 25/3
So, Speed of the faster train = 2(25/3) = 50/3 m/s = (50/3*18/5)km/hr = 60km/hr
