The person traveling at the speed of D = 8t up, where D is the distance from the starting point and t is time. t = D / 8 travels at the speed of t = D / 6 to the floor. Climbing, travel D / 8 per hour and starts at point 0 Go down that travel D / 6 per hour and starts at D / 8 * t D. point = D – D / 6 * t Dt / 8 = D – Dt / 6 = 6Dt 48D – 8DT 6t = 48 – 8t 14 t = 48 3 7.3 hours t = At 8 plus 3 hours to the nearest 7.3 seconds, the time is 11:25:43 am Not calculation.
