    A man travelling in a car count 19 telephone poles in one minute. If each pole is 50 m apart, then at what speed is the man sitting in the car travelling?

    A)  54 km/hr                      

    B)  45 km/hr

    C)  56 km/hr                      

    D)  50 km/hr

    Correct Answer: A

    Solution :

     A man travelling the car count 19 poles in a minute. Distance between two poles = 50 m. \[\therefore \]  Distance between 19 poles \[=~\,\,18\times 50=900\text{ }m\] Speed of man sitting in car \[\frac{\text{Distance}}{Time}\] \[=\frac{900}{60}=15\times \frac{18}{5}=\underline{\mathbf{54}\,\mathbf{km/hr}}\]
