Question
The speed of a motorboat in still water is 50 km/hr. If
the motorboat travels 120 km along the stream in 1 hour 30 minutes, then the time taken by it to cover the same distance against the stream will beSolution
Let the speed of the current be x km/hr Rate Downstream = (x+ 50) km/hr According to the question 120/(x+50) = 1 hour 30 minutes 120/(x+50) = 3/2 240 = 3x + 150 x= 30 km/hr Rate upstream = 50 – 30 = 20 km/hr Required time = 120/20 = 6 hours
