Bob leaves point A and drives due west to point B. From point B, he drives due south to point C. How far is Bob from his original location?

1) Point A is 24 miles from point B.
2) Point B is 18 miles from point C.

OA C

Certainly, each statement is insufficient. Let's combine them.

From the given information, we know that points A, B and C for a right-angled triangle, in which /_B = 90º. We have to get the value of AC.

AC = √(AB^2 + BC^2) = √(24^2 + 18^2) = √900 = 30. Sufficient.

The correct answer: C

Hope this helps!
