Question

a train 280m long is running at a uniform speed of 90km/hr.find the time taken by it to cross a man standing on the platform?

Answer 1

Answer:

Time taken by the train to cross a man standing on the platform is 11.2 sec.

Step-by-step explanation:

• Length of the train = 280m
• speed of the train = 90km/hr

Therefore,

• Time taken = $\frac{280}{(90 \times \frac{1000}{3600} )}$

On solving we get,

$\frac{280 \times 3600}{90 \times 1000}$

$\frac{112}{10} sec$

That means it takes 11.2 sec ..
