    km. Arjun travels at a speed of 75 km/hr and Bittu at 25 km/hr. The total time they spent traveling is 4.4 hours. Calculate the distance that Arjun covered.

    C 65 km Correct Answer Incorrect Answer
    D 79 km Correct Answer Incorrect Answer
    E none of these Correct Answer Incorrect Answer

    Solution

    ATQ, Let the distance covered by Arjun be 'd' km. Therefore, distance covered by Bittu = (150 – d) km According to the question, d/75 + (150 – d)/25 = 4.4 Or, {d+ 3(150 – d)} × 75 = 4.4 2d = 450 – 75 × 4.4 Or, 2d = 450 – 330 Or, d = 120/2 = 60 km
