A ship is leaving a port. It takes 240 seconds to passes through a 750m channel to get to the port gates, and takes 60 seconds to pass through the gates of the port. What is its length?
Correct answer: D
Explanation
Let the length of the ship be x metres and its speed be y m/sec. Then, x / y = 60 ⇒ y = x / 60
∴ (x + 750) / 240 = x / 60 ⇔ x = 250 m. Answer D
