PLEASE HELP!! I will award 60 points! I need help with part 2
Consider a lifeguard at a circular pool with diameter 43 meters. The lifeguard, at position A, must reach someone who is drowning on the exact opposite side of the pool, at position C. The lifeguard swims at a rate of 1.22 m/s and runs at a rate of 3.26 m/s.
Part 1: Find a function T, that measures the total amount of time it takes to reach the drowning person as a function of the swim angel theta?
CORRECT ANSWER I GOT: (43cos(theta)/1.22)+(43(theta)/3.26 )
Part 2: HELP
At what angle theta should the lifeguard swim to reach the drowning person in the least amount of time?
