A train is travelling at the speed of 96 kilometres per
hour. It takes 3 seconds to enter a tunnel and 30 seconds more to pass through
it completely. What is the length of the train and the tunnel?
Answer: Length of
the train 80 metres. Length of the tunnel 800 metres.
Length of the train = 96 x 3 /60x60 km = 80 metres
Length of the tunnel = 96x30 / 60x60 km = 800 metres.
