Question 30

If train A travels at a 50kph in 2hrs, and train B travels at 70kph, how long would train B meet train A

Answer 30

To calculate when Train B will meet Train A, let's consider their relative speeds and distances traveled. Step 1: Find the head start of Train A Train A travels at 50 kph for 2 hours, so the distance it covers is: Distance of Train A = 50 \times 2 = 100 This means Train B starts 100 km behind Train A --- Step 2: Find the relative speed Since Train B travels at 70 kph and Train A at 50 kph, their relative speed is Relative Speed = 70 - 50 = 20kph --- Step 3: Calculate the time for Train B to catch Train A The time it takes for Train B to close the 100 km gap is: Time= Distance Speed}} = 100/20= 5 hrs --- Final Answer: Train B will meet Train A after 5 hours.
