Please help me with this problem and be as detailed as possible about it.

5-65. Jade is having a wonderful time riding a merry-go-round. Her distance d (in feet) from the fence nearest the entrance is given by the equation d = 25 sin (15+ 35 where t is the time in seconds since the merry-go-round started to rotate. a. How close can Jade be to the fence? How far? b. How long does it take for the merry-go-round to complete one revolution? C. How long before Jade is 60 feet from the fence for the second time? d. Sketch the graph of d vs. t. Label and scale (put numbers on) the axes appropriately
