Answer 2

Wesley sailed his boat due north for 18 miles, then due east for another 18 miles.

Wesley started from point A, sailed his boat in north direction for 18 miles and reached B. From B, he sailed 18 miles towards east. He stopped at C.

Use Pythagoras theorem to find the distance between A and C

`AC^2 = AB^2 + BC^2`

`AC^2 = 18^2 + 18^2`

`AC^2 = 648`

`AC =√(648)`=25.46 miles

Wesley is approximately 25.46 miles from where he began.
