    Cars \[{{C}_{1}}\] and \[{{C}_{2}}\] travel to a place at a speed of 30 and 45 km/h respectively. If car \[{{C}_{2}}\] takes \[2\frac{1}{2}\] hours less time than \[{{C}_{1}}\] for the journey, the distance of the place is

    A)  300 km             

    B)         400 km            

    C)  350 km            

    D)        225 km            

    Correct Answer: D

    Solution :

    Let \[{{C}_{1}}\] takes t hrs. Then, \[\because \]  Distance is same. \[\therefore \]   \[30t=45\left( t-\frac{5}{2} \right)\] \[\Rightarrow \]   \[t=\frac{15}{2}\] \[\therefore \] Distance \[=30\times \frac{15}{2}=225\,km\]
