Question

how long will a train 330m long travelling at40km/h take to cross a platform 110m long how long will it take to pass a man sitting on the platform
​

Answer 1

Answer:

39.6 Secs

29.7 Secs

Step-by-step explanation:

Speed of train = 40 km/Hr

Train length = 330 m

Platform length = 110m

Distance need to travel to cross platform = 330 + 110 = 440 m

440 m = 440/1000 km = 0.44 km

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

$Time = \frac{0.44}{40}$

Time = 0.011 Hr

Time = 0.011 × 3600 = 39.6 Secs

To cross Man

Distance to be covered = 330 m = 0.33 km

$Time = \frac{0.33}{40}$

Time = 0.00825 Hr

Time = 0.00825 × 3600 = 29.7 Secs
