The first successful ascent to the summit of K2, the world's second highest and most dangerous mountain was July 31, 1954. The distance (in meters) the climbers ascended K2 is modeled by the graph below. Determine the average rate of ascent from point A ("Base Camp") to point B ("Camp IV").
(a) Determine the average rate of ascent from point A ("Base Camp") to point B ("Camp IV").
(b) Estimate the instantaneous velocity of ascent of the climbers at Camp IV.
(a). 1666.7 m/week
(b). 1245.5 m/week
(c). 612.2 m/week
(d). 166.7 m/week
(e). none of the above
