Question

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

Answer 1

Answer:

4 cm (72 ÷ 18 = 4). 4 cm in map covers a distance of 72km

Answer 2

$x_{1}=1 and x_2=?$

$y_1=18 and y_2=72$

Now,

$\frac{x_1}{y_1} = \frac{x_2}{y_2}$

$= > \frac{1}{18} = \frac{x_2}{42}$

$⇒x_2=4 cm$
