Question
Two individuals, P and R, travel from point L to point K
at different speeds. P takes 11 hours to complete the journey, while R takes 13 hours. The difference in their speeds is 7 km/h, with one traveling faster than the other. Determine the distance between points L and K.Solution
Let distance = D km P's speed = D/11 R's speed = D/13 |D/11 - D/13| = 7 (13D - 11D) / 143 = 7 2D / 143 = 7 2D = 1001 D = 500.5 Distance = 500.5 km
