    A car takes 6 hours to reach a destination by travelling at the speed of 50 km per hour. How long will it take when the car travels at the speed of 75 km per hour?
    Ans : Time : Distance :: Time : Distance
    6 : 50 km :: x : 75
    ∴ By inverse proportion
    6 × 50 = x × 75
    ⇒ x = (50 × 6)/75
    = 4 hours
