A train 200 metres long is moving at the rate of 40 kmph. In how many ...
The correct answer is D as 
time = Length of train / speed of train
time = 0.20 km / 40 km/h
time = (0.20 / 40) h
time = 5×10⁻³ h and to convert it to seconds just multiply it by 3600 s/h
time = 5×10⁻³ h * 3600 s/h the unit h is cancelled and the unit seconds remain
time = 18 seconds
