Question

a girl walks 200m towards east and then she walks 150m towards west .find the distance of the girl from the starting point

Answer 1

dis covered towards east=200m
dis covered towards west=150m
total dis of girl from starting point=200+150=350m

Answer 2

Answer:

250m

Step-by-step explanation:

we need to find the distance FROM the starting point TO the north (150m),

using pythagoras theorem,

$c=\sqrt{a^{2} +b^{2} }$

insert the values,

$\sqrt{(200^{2}+150^{2}) }$

$=$ $\sqrt{40000+22500}$

$= \sqrt{62500}$

= 250m

hence, the distance from the starting point to the current point is (north) 250m
