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

Harold Stephen Black

Died 11 Dec 1983 at age 85 (born 14 Apr 1898).American electrical engineer who discovered and developed the negative-feedback principle, in which amplification output is fed back into the input, thus producing nearly distortionless and steady amplification. In 1921, Black joined the forerunner of Bell Labs, in New York City, working on elimination of distortion. After six years of persistence, Black conceived his negative feedback amplifier in a flash commuting to work aboard the ferry. Basically, the concept involved feeding systems output back to the input as a method of system control. The principle has found widespread applications in electronics, including industrial, military, and consumer electronics, weaponry, analog computers, and such biomechanical devices as pacemakers.
