A girl travels 12km due west, then 5km due north . How far is she from the starting point

Answer 1

The girl is 13 km away from the starting point.

This can be calculated using the Pythagorean theorem:

Distance = Square root of ((12^2) + (5^2))
Distance = Square root of (144 + 25)
Distance = Square root of 169
Distance = 13

Therefore, the girl is 13 km away from the starting point.
