What is the distance from point A to point B?

[kcblues]

A man starts at point A and walks 30 ft., turns right and walks another 30 ft., turns left and walks another 10ft. to point B. How far is he from point A (in a straight line)?

50 ft

Yep, I'm with Mike; 50ft.

if you are talking about the marlboro clue 20 "Haw" means to turn back toward the driver not turn left. Go to googles and type in all three commands and you will get the definitions of 'em.

Boy, I went to the web site and discovered a new one. It actually said left turn(turn toward driver). The others that I have been finding all just said to turn toward driver and I thought it meant go back 10 feet. Lucky that I found it in time. Now I can do my math. Good luck with your answer. If I come up with something different then the two above I will let you know.

[kjmckinnon46]

Yes my daughter called me and 50 feet is the correct answer. Good luck and sorry if I confused anybody with the wrong answer. I differently was not trying to lead anyone down the wrong path. I honestly thought it was turn back toward driver and go 10 feet making it 36.1

If you combine the last 10 feet with the first 30 feet, you have got what is basically a 3-4-5 triangle.  So the answer (as the others have said) is 50ft.  Or if you prefer, slightly less than 50 feet due to the curvature of the Earth.

[kempie]

Over such small distances any effect of the Earth's curvature would be negligible compared to the difference caused by a change in altitude as you walked.

[bernardo]

Assuming that the surface of the Earth is a perfect sphere with no hills or other such irregularities, and that the radius of the Earth is 3900 miles, a path of 50 feet along the curved surface from A to B would produce a straight-line distance (through the fabric of the Earth) from A to B of approximately 50 feet minus a 6,200,000,000th of an inch.

50 Ft is right.  Good Job!!!!!!!!!!!!!!
