Question 1
Two runners start from the same point on a circular track of length 655 m. Their speeds are 7 m/s and 13 m/s. If they run in opposite directions, when will they meet?
Step-by-step:
1. Relative speed (opposite direction) = 7 + 13 = 20 m/s
2. Time to meet = Track length / Relative speed = 655 / 20 = 32.8 seconds
1. Relative speed (opposite direction) = 7 + 13 = 20 m/s
2. Time to meet = Track length / Relative speed = 655 / 20 = 32.8 seconds
