The angle of elevation from the first team to the stranded climber is 16 °. The angle of elevation from the second team to the climber is 24°. What is the altitude of the climber? Round to the nearest hundredth of a mile.

The formula v = √2.6r models the maximum safe speed, v, in miles per hour, at which a car can travel on a curved road with radius of curvature r, in feet. A highway crew measures the radius of curvature at an exit ramp on a highway as 670 feet. What is the maximum safe speed?
For this problem, round your answer DOWN to the nearest whole number. (Think: Why is this type of rounding appropriate for this scenario?)
