Question
A boat covers a distance of 75 km downstream in 2.5
hours. If the ratio of upstream speed to downstream speed of the boat is 3:5, then find the distance travelled by the boat in upstream in 10 hours.Solution
ATQ: Let the upstream and downstream speed of the boat be '3x' km/hr and '5x' km/hr, respectively. ATQ, 5x = (75/2.5) So, 'x' = 6 So, upstream speed of the boat = 3x = 3 × 6 = 18 km/hr Required distance = 18 × 10 = 180 km
