Question

    Sneha cycles to her tuition class at a speed of 20 km/h and

    ends up reaching 3 hours late. Had she pedalled at 25 km/h, she would have reached exactly on time. Determine the total distance Sneha covered.
    A 415 km Correct Answer Incorrect Answer
    B 209 km Correct Answer Incorrect Answer
    C 322 km Correct Answer Incorrect Answer
    D 300 km Correct Answer Incorrect Answer

    Solution

    ATQ,

    (Let the actual time Sneha should take to reach the class = 't' hours

    Let the total distance = 'd' km

    We have,

    20(t + 3) = 20t + 60 = d

    Also,

    25t = d

    So, 20t + 60 = 25t

    So, 5t = 60

    So, t = 12

    So, d = 25t = 25 × 12 = 300 km
