Question

A goods train runs at the speed of 72 kmph and crosses a 250 m long platform in 26 seconds. What is the length of the goods train?

• A. 230 m
• B. 240 m
• C. 260 m
• D. 270 m

Answer 1

The correct option is D 270 m

$Speed=(72\times \frac{5}{18})m/sec=20m/sec.$
$Time=26sec.$
Let the length of the train be x metres.
Then, $\frac{x+250}{26}=20$
$\Rightarrow x+250=520$
$\Rightarrow x=270$
