After visiting my Great Aunt...
[5499] After visiting my Great Aunt... - 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? - #brainteasers #math #riddles - Correct Answers: 29 - The first user who solved this task is Djordje Timotijevic

Granville T. Woods

Died 30 Jan 1910 at age 53 (born 23 Apr 1856). American inventor who held numerous patents in diverse fields. As the most prolific black inventor by career of the late 19th and early 20th century in the U.S., he has been called the Black Edison. Wood's first patent (3 Jun 1884) was for a locomotive steam boiler. He started the Woods Electric Company, in Cincinnati, Ohio, to commercially develop a variety of electrical devices. In 1887 he patented his Synchronous Multiplex Railway Telegraph, which enabled moving railway trains to maintain communications links thus avoiding accidents. His other patents included a telephone transmitter, an electric railway, an electric incubator for hatching chickens (1900) and an important safety device - an automatic air-brake for railroad use (10 Jun 1902).«
