उत्तर

Distance (in km) 50 x
Time (in minute) 60 12
Let the distance be x km.
\[\text{ If the time taken is less, the distance covered will also be less }  . \]
\[\text{ Therefore, it is a direct variation }  . \]
\[50: x = 60: 12\]
\[ \Rightarrow \frac{50}{x} = \frac{60}{12}\]
\[ \text{ Applying cross muliplication, we get: } \]
\[x = \frac{50 \times 12}{60}\]
\[ = 10\]
\[\text{ Thus, the required distance will be 10 km } .\]
