Question
The speeds of Arun and Bhanu are
in the ratio of 3:4, respectively. Both begin their journey simultaneously to cover a distance of 13.5 km. Bhanu completes the distance 15 minutes earlier than Arun. Determine Arun's speed.Solution
ATQ,
Let the speed of Arun and Bhanu be 3x km/hr and 4x km/hr, respectively. So, time taken by Arun and Bhanu be 4x hour and 3x hour, respectively. 4x – 3x = 15/60 x = 0.25 So, time taken by Arun = 4x = 1 hour Distance = 13.5 km Required speed of Arun = 13.5 km/hr
