Question

Rahul walks 2/5 km from a point A, towards North and then from there 1 1/2 km towards south. At what position Will he be from point A? ​

Answer 1

Answer:

5.1 km from point A

Step-by-step explanation:

11/2 km - 2/5 km = 5.1 km

Answer 2

Given: Rahul walks $\[\frac{2}{5}\]$ km from a point A, towards North and then from there $1\frac{1}{2}$ km towards south.

To determine: the distance between point A from his last position.

Solution:

Draw the required figure.

Find the position will Rahul be from point A.

distance$\[ = 1\frac{1}{2} - \frac{2}{5}\]$

             $\[ = \frac{3}{2} - \frac{2}{5}\]$

             $\[ = \frac{{15 - 4}}{2}\]$

             $\[ = \frac{{11}}{2}\]$

Therefore, Rahul will be $\frac{11}{2}$km from the point A.
