Question 1
Two runners start from the same point on a circular track of length 471 m. Their speeds are 8 m/s and 9 m/s. If they run in the same direction, when will they meet again?
Step-by-step:
1. Relative speed (same direction) = |9 - 8| = 1 m/s
2. Time to meet = Track length / Relative speed = 471 / 1 = 471.0 seconds
1. Relative speed (same direction) = |9 - 8| = 1 m/s
2. Time to meet = Track length / Relative speed = 471 / 1 = 471.0 seconds
