Renu was sitting inside Train A, which was travelling at 50 km/hr. Another Train B, whose length was three times the length of A and crossed her in opposite direction in 15 seconds. If the speed of Train B was 58 km/hr, then the length of Train A (in m) is ?
Show answer & explanation
Correct answer: D
Explanation
The correct answer is option 4 ie 150.
Renu = 50 km/hr
Train = 58 km/hr
S = 108 km/hr
= 30m/s
3x = 30 × 15
x = 450 / 3
x = 150
