Answer 1

Answer:

The answer is 3 km.I will follow u but pleasssssse follow me back.thanks

Answer 2

Answer:

5 km

Step-by-step explanation:

Draw a figure according to the given directions.

Construction : (i) Draw a line parallel to the southern path joining the end point and the western path at the point vertically opposite to the end point.

(ii) Join the starting point and the end point.

Now,

We get a right-angled triangle where,

Base = 4 km

Altitude = 3 km

We have to find the displacement ,i.e, the hypotenuse.

According to Pythagoras theorem,

$hypotenuse^{2} = base^{2} + altitude^{2}$

Here,

$Displacement^{2} = 4^{2} + 3^{2}$

i.e, $Displacement^{2}$ = 16 + 9

                             = 25

Therefore,displacement = $\sqrt{25}$

                                        = 5 km.
