Question
A 150-meter-long train requires 'p' seconds to pass a
tree. When the train runs at 75% of its original speed, it takes 20 seconds to pass a 90-meter-long tunnel. Determine the value of 'p'.Solution
ATQ, Let the speed of the train be 'u' meters per second. 
At 75% of the original speed, the speed becomes 0.74u The total distance to cross the tunnel = 150 + 90 = 240 meters. 
From Equation I and II, 
The value of 'p' is 12.5 seconds.
