A forest ranger is watching the progress of a forest fire spreading towards her from the top of a 3033-foot mesa. In 6 minutes, the angle of depression to the leading edge of the fire changes from 10.9° to 12.29º. How many feet does the fire advance during the 6 minutes that the ranger is observing it? (Round your answer to two decimal places.) At what speed (in MILES PER HOUR) is the fire spreading towards the ranger? (Round your answer to two decimal places.)
