Solution 1

Step 1: Convert the speed of A from km/hr to m/s. We know that 1 km/hr = 5/18 m/s. So, A's speed = 5*(5/18) = 25/18 m/s.

Step 2: Calculate the time taken by A to cover 100m. Time = Distance/Speed = 100/(25/18) = 72 seconds.

Step 3: Since A beats B by 8 seconds, the time taken by B to run 100m - 8m Knowee AI StudyGPT is a powerful AI-powered study tool designed to help you to solve study prob
