Two boats A and B start towards each other from two
places, 660 km apart. Speed of the boat A and B in still water are 30 km/h and 25 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. (30 - x)t + (25 + x)t = 660 30t + 25t = 660 55t = 660 t = 12 hours
