A train 280 m long running with a speed of 63 km/hr will pass a tree in how many seconds?
Answer & explanation
Correct answer: option 1
Speed = \(\frac{Distance }{Time }\)
63 x \(\frac{5 }{18 }\) = \(\frac{280 }{Time }\)
\(\frac{35 }{2 }\) = \(\frac{280 }{Time }\)
Time = \(\frac{280 x 2 }{35}\)
Time = 16 seconds
