John is trying to get from point A to point C, which is 20 miles away to the northeast; however the direct road from A to C is blocked and John must take a detour. John must travel due north to point B and then drive due east to point C. How many more miles will John travel due to the detour than if he had traveled the direct 20 mile route from A to C?
(1) The ratio of the distance going north to the distance going east is 4 to 3
(2) The distance traveled north going the direct route is 16
Can we get this Geometry + TSd type of questions in actual GMAT
This question is discussed here:

- GMAT Syllabus for Focus Edition
- Geometry Tested on GMAT Focus?
While specific geometry knowledge is not tested on GMAT Focus,
not everything involving shapes, volumes, or areas requires specialized geometry knowledge. The area of a square or rectangle, the volume of a cube or rectangular solid, and
the Pythagorean theorem are not considered specific geometry knowledge by the GMAT and can still be tested. Moreover, a question can involve shapes but test another area, such as combinations or other topics. There are several
questions involving these concepts in the GMAT Prep Focus mocks.
The chapter on coordinate geometry, including planes and slopes, is still present in the recent Official Guides. That said, it is tested to a much smaller extent. For example, you might see some questions involving graphs, either in Problem Solving or in Data Insights graph-based questions. However, those usually fall under the functions category rather than pure coordinate geometry, so they typically won’t involve distance calculations, angles, or similar topics.
