Answer 1

$\bf \huge \underline \pink{correct \: question}$

a train 280 metres long is running at a speed of 42 kilometre per hour how much time will it take to pass a man standing on a platform?

$\bf \huge \underline \green{answer}$

Speed = 42 km/h or 42000 metres ,

Distance / Train length =

42,000 metres ÷ 3600 seconds =.11.666 metres per second Train = 280 metres long ÷ 11.666 = 24 seconds

The Time required is 24 seconds the 280 metre train will take to pass the man while the trains spèed is 42 km/h.

Answer 2

$\huge{GIVEN:}$

I think that the length of the train is 280M

★ speed=$42km$per hour

★ distance=$280M$

$\huge{solve:}$

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

=$280÷\frac{700}{60}$

=$\boxed{24s}$
