Question
A boat covers a distance of 240 km downstream in 8
hours. If the ratio of upstream speed to downstream speed of the boat is 2:5, then find the distance travelled by the boat in upstream in 15 hours.Solution
ATQ, Let the upstream and downstream speed of the boat be '2x' km/hr and '5x' km/hr, respectively. ATQ, 5x = (240/8) So, 'x' = 6 So, upstream speed of the boat = 2x = 2 × 6 = 12 km/hr Required distance = 12 × 15 = 180 km
