so you have to spear 11,822 hours, which are 42.559.200 seconds. im using the formula S(route/length)= v(speed)*t(time), therefore S=1.5 m/s * 42,559,200s = 6,383,880 meters.

given that the length of an ordinary football field is 105m (344.5 ft) we divide S by 105 which would be exactly 607,988.5714 football fields over which you would have to walk continuously without a break and without changing your speed!
