    speeds which are in the ratio 5:3 respectively. Ajay left the place 36 seconds after Vishal. If after 72 seconds of the departure of Vishal, Ajay is 60 meters apart from Vishal, then find the speed of Vishal.

    B 12 km/hr Correct Answer Incorrect Answer
    C 15 km/hr Correct Answer Incorrect Answer
    D 20 km/hr Correct Answer Incorrect Answer
    E 18 km/hr Correct Answer Incorrect Answer

    Solution

    Let the speeds of Ajay and Vishal be 5x and 3x km/hr respectively. Distance covered by Vishal in 72 seconds = 3x x (5/18) x 72 = 60x m Distance covered by Ajay in 36 seconds = 5x x (5/18) x 36 = 50x m According to the question, => 60x тАУ 50x = 60 => x = 6 Therefore the speed of Vishal = 3x = 18 km/hr
