Question
Train A leaves a station at a certain time and at a
fixed speed. After 4 hours, Train B leaves the same station and moves in the same direction at a uniform speed of 140 kmph, this train catches up Train A in 3 hours. Find the speed of Train A.Solution
Let the speed of the Train A = x kmph. Distance covered by Train A in 7 hrs = Distance covered by Train B in 3 hrs So, 7x = 3 × 140 => x = 60 So, Speed of Train A = 60 kmph
