Question 1
Two runners start from the same point on a circular track of length 514 m. Their speeds are 7 m/s and 15 m/s. If they run in opposite directions, when will they meet?
Step-by-step:
1. Relative speed (opposite direction) = 7 + 15 = 22 m/s
2. Time to meet = Track length / Relative speed = 514 / 22 = 23.4 seconds
1. Relative speed (opposite direction) = 7 + 15 = 22 m/s
2. Time to meet = Track length / Relative speed = 514 / 22 = 23.4 seconds
