Aunt's Ol' Jalopy

Math brain teasers require computations to solve.

 Fun: (2.98) Difficulty: (1.55) Category: Math Submitted By: firefox99

After visiting my Great Aunt Annie, I travelled home in her old jalopy. The car was old and battered, it had a leak from the petrol tank, and I was stuck in second gear.

This meant that I could only travel along at a steady 30 miles per hour and managed a paltry 20 miles per gallon of fuel.

At the start of the journey I had placed exactly 10 gallons of fuel into the tank. I knew though, that the fuel tank lost fuel at the rate of half a gallon per hour.

Just as I arrived home, the car stopped because it had run out of fuel and I had only just made it.

How far was it from my Great Aunt's to my home?

 Posted by Melanmel16 on Mar 28, 2012 Great aunt Annie lol Posted by Babe on Apr 24, 2012 I did not even try. Did not like math in school and certainly was not going to bust my brain on this one. How about a real quiz that doesn't take us back to the class room!! Posted by HABS2933 on Apr 24, 2012 Great teaser, easily solvable. Posted by bestgirl on Apr 24, 2012 Good one. Posted by dsjt on Apr 24, 2012 Where did your aunt find a "jalopy" that jets 20 MPG? I wished my vehicle could get that. Posted by xdbtcp on Apr 24, 2012 I figured 20 miles per gallon, and you had 10 gallons, so you went 200 miles... Posted by xdbtcp on Apr 24, 2012 Guess I shoulda read "the fuel tank lost fuel at the rate of half a gallon per hour." Posted by gghali on Apr 24, 2012 Great teaser! Lots of fun. Posted by wordmama on Apr 24, 2012 I love math, even though it's not my field. I wanted to try it, but I couldn't figure out how to reconcile the mpg, the mph, and the fuel loss. The explanation was excellent; I'm disappointed in myself that I couldn't see it on my own! Posted by FatHead on Apr 24, 2012 That was awesome. I'm glad I had as much practice as I did with high-school algebra and word problems. Posted by bradon182001 on Apr 24, 2012 Nice teaser, never hurts to practice a little math to keep the mind active. Posted by auntiesis on Apr 24, 2012 I love math problems, but this one was way too easy. But I still loved it. Posted by luluw5 on Apr 24, 2012 this is supposed to b a brain teaser! not homework! Posted by DarylK on May 25, 2012 Ah, I shoud have read the question throughly.
