The speed ( in kmph) of a person who crosses a 1200 meter long bridge in 12 minutes is

Solution

Speed of the person = $$\frac{1200}{12}=100\ \frac{meters}{\min}$$

Multiplying both numerator and denominator by 60 (because we want speed in kmph), 
We get Speed = $$6000\ \frac{meters}{hour}=6\ kmph$$
