Speeds of train P and Q is 65 m/s and 50 m/s. Train P and Q are running in same direction. They cross each other in 50 seconds. What is total length (in metres) of trains P and Q?
Show answer & explanation
Correct answer: B
Explanation
Given:
Speeds: P = 65 m/s, Q = 50 m/s
Time = 50 seconds
According to the formula:
Relative Speed = 65 − 50
Total Length = Relative Speed × Time
Relative Speed = 15 m/s
Total Length = 15 × 50 = 750 meters
