उत्तर
Let the distance travelled in 315 minutes be x km.
| Time (in minute) | 125 | 315 |
| Distance(in metre) | 100 | x |
\[\text{ If the distance travelled is more, the time needed to cover it will also be more . } \]
\[\text{ Therefore, it is a direct variation } . \]
\[\text{ We get: } \]
\[125: 315 = 100: x\]
\[ \Rightarrow \frac{125}{315} = \frac{100}{x}\]
\[\text{ Applying cross muliplication, we get: } \]
\[x = \frac{100 \times 315}{125}\]
\[ = 252\]
\[\text{ Thus, Anupama would cover 252 metre in 315 minutes } .\]
