Two boats X and Y start towards each other from two
places, 168 km apart. Speed of the boat X and Y in still water are 11 km/hr and 13 km/hr respectively. If X proceeds down and Y up the stream, they will meet after.Solution
Let the speed of the stream be x km/hr and both the boats meet after t hours According to the question, ⇒ (11 + x) t + (13 – x) t = 168 ⇒ 11t + 13t = 168 ⇒ 24t = 168 ⇒ t = 168/24 = 7 hours
