    Topic Progress:

    Today, We are going to take a test on Problems based on Height and Distance.

    Before you take the test read these posts to be comfortable.

    Shortcuts and Tips for Height and Distance Problems                                                

    Important Formulae

    1. Speed = [Distance/Time],
    Distance = (Speed*Time)
    2. x km/hr = [x*5/18] m/sec.
    3. If the ratio of the speeds of A and B is a:b, then the ratio of the times taken by them to cover the same distance is 1/a : 1/b or b:a.
    4. x m/sec = [x*18/5] km/hr.
    5. Suppose a man covers a certain distance at x km/hr and an equal distance at y km/hr. then, the average speed during the whole journey is [2xy/x+y] km/hr.
