A man goes $24$ m due west and then $7$ m due north.How far is he from the starting point?

• A. 23
• B. 24
• C. 25
• D. none

Answer 1

The correct option is C 25

According to Pythagoras theorem,

$7^2+{24}^2=x^2$

$\Rightarrow x^2=49+576$

$\Rightarrow x^2=625$

$\Rightarrow x=\sqrt{625}=25$m

$25$m far from the starting point.
