Two boats A and B start towards each other from two
places, 528 km apart. Speed of the boat A and B in still water are 18 km/h and 15 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. (18 - x)t + (15 + x)t = 528 18t + 15t = 528 33t = 528 t = 16 hours
