Title: This will sink as Titanic did! Math problem Post by: vlajce on November 02, 2015, 01:40:53 AM 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? Title: Re: This will sink as Titanic did!

I'll the answer in a sec. 190 miles EDIT: I am wrong according to an answer I found via Google. Off by two score. Title: Re: This will sink as Titanic did!
