question_answer 1)

                Rashmi has a road map with a scale of 1 cm representing 18 km. She drives on cl road for 72 km. What would be her distance covered in the map?

Answer:

                Let the distance covered in the map be x cm. Then, \[1:18=x:72\] \[\Rightarrow \]               \[\frac{1}{18}=\frac{x}{72}\] \[\Rightarrow \]               \[x=\frac{72}{18}\] \[\Rightarrow \]               \[x=4\] Hence, the distance covered in the map would be 4 cm.
