Question

A train 240 m long passes a pole in 24 seconds. How long will it take to pass a platform 650 m long?

• A. 65 sec
• B. 89 sec
• C. 100 sec
• D. 150 sec

Answer 1

The correct option is B 89 sec

We know,

$Speed=\frac{distance}{time}$

$Speed=\left(\frac{240}{24}\right)m/sec=10m/sec.$

$Time=\frac{Distance}{Speed}$

$\therefore$ Required time $=\left(\frac{240+650}{10}\right)Sec=89Sec$
