Billy lives at the NW corner of a 7.5 minute topographic map, and his coordinates are 33 degrees, 07 minutes, and 30 seconds North and 95 degrees and 30 minutes West.  One day, he wants to go out to eat.  Luckily, there is a fast food restaurant at 33 degrees, 05 minutes North and 95 degrees, 27 minutes, 30 seconds West.  Giving your exact answer in minutes, how far away is Billy from the fast food restaurant?
3.53 minutes? Not too sure
That is correct, but I would have preferred it rounded correctly (the calculator gave me 3.535 something, which rounds to 3.54.) Your turn.
Could someone explain this answer to me? I've never done this type of problem before.

How I did it was i first found the total minutes for latitude and longitude. From the first latitude to the latitude it was a total of 2 1/2 minutes. From first longitude to the second longitude it was also 2/12 minutes. Finally I did the distance formula (the one that is similar to the Pythagorean theorem

For Regionals and States, the rules say that Latitude and Longitude should be written at an introductory level. Also, most people will have learned this math before. For example, there are trigonometry tricks that really help with this event, but test writers assume most people haven't learned trig when writing tests, and so these tests are geared towards younger people (this is division B).

Also, drawing a diagram would've made this problem much easier, as you would be able to recognize that this is an isosceles right triangle, which would mean that the hypotenuse is .

Pettywap, your turn.

This makes a lot of sense. Tysm!

scale 1:125,000

While hunting deer, Albert Einstein is bear hunting. Einstein decided to climb Mt. Froggie, which has an elevation of 21,000 ft and run to Mt. Petty, which has an elevation of 35,000 ft. and climb it. As a stalker you have decided to track Albert's movement. On a map you have measured 17 inches between Mt. Froggie and Mt. Petty. What was the total distance Albert Einstein traveled?

10% chance this is right 33.54 miles?

This was not a very thought out question but I did not get that. In miles it got 44.14 but I could be wrong :(

I believe you're right; I forgot to factor in elevation. Your answer is correct though. Wouldn't you need the elevation of the lowest point in between to get the most accurate answer for that question though?

Thats why I said it wasn't a very thought out question. I should have put a contour interval and then it would be the most accurate as you said. :)
