Rajdhani Train running at a speed of 54 km/hr crosses a platform of length same as that of the train in 36 sec. If a Duronto train, which is 230 meters long crosses the same platform in 25 sec, then find speed of Duronto train (in km/hr)?
🎥 Video solution / Text Solution of this question is given below:
Speed of Duronto Train
Step 1: Rajdhani crosses a platform equal to its length in 36 sec.
Let length of Rajdhani = L meters ⇒ Platform = L meters ⇒ Total distance = 2L meters
Speed = 54 km/hr = 15 m/s
So, 2L = 15 × 36 = 540 ⇒ L = 270 m
Step 2: Duronto (length 230 m) crosses same platform (270 m) = total distance = 500 m
