Question
Two boats A and B start towards each other from two
places, 600 km apart. Speed of the boat A and B in still water are 23 km/h and 17 km/h respectively. If A and B proceeds against and with the stream, respectively then after how much time will they meet?Solution
Let the speed of stream be ‘x’ km/h and they meet after‘t’ hours According to question, Distance covered while going upstream + Distance covered while going downstream = Total distance covered. (23 - x)t + (17 + x)t = 600 23t + 17t = 600 40t = 600 t = 15 hours
