Question
A train takes 8 seconds to pass a
dog running in the opposite direction to the train at a speed of 10 m/s. Given that the train is 400 meters long, determine the train's speed.Solution
ATQ, Let assume the speed of the train is 'p' m/s ATQ; 400 = (10 + p) × 8 Or, 400 = 80 + 8p Or, (400 - 80) = 8p Or, 8p = 320 Or, p = 40 Required speed of the train = 40 m/s
499.98% of (√440.8 + 12.922 ) - 12.02 of 4.82 = ? of 9.82 + 9.98% of 999.94
44.89% of 600.25 + (29.98 × 5.67) + (√1940 – 10.29) = ?2
Two trains, 'P' and 'Q', are moving with speeds of 16 m/s and 24 m/s, respectively. The lengths of the trains are in the ratio 3:...
