 Puzzle ID: #10475 Fun: (2.7) Difficulty: (1.75) Category: Math Submitted By: Bobbrt

Glenn and Steve took turns driving on a trip to Boston and back. Glenn drove the first 40 miles and Steve drove the rest of the way to Boston. On the way back, Glenn started to drive, and then Steve drove the last 50 miles.

Which of the two drove more, and how much more did he drive?

 jimrcook Mar 11, 2003 Using G for the distance that Glenn drove, S for Steve's distance, and D for the total between "there" and Boston: Glenn drove 40 miles, plus all but 50 miles of the way back. G=40+(D-50). This is the same as G=D-10. Steve drove all but 40 miles, plus 50 miles on the way back. S=(D-40)+50. Simplifying again gives S=D+10. As the answer showed, clearly S is 20 more than G. Nice puzzle. Thinker_thought May 20, 2004 This is like...Dude! How could you figure that out? Dude, I know...I know, I sound stupid, but...DUDE! hottie13 May 20, 2004 i thought this was fun but it was easy at the same time. good job! vbfreak55 May 20, 2004 Good one! This wasn't too hard, to where you'd get frustrated with it, but it also wasn't like so encredibly easy, either. Nice Job! paul726 May 26, 2006 Nice, compact, well done!
