3. The time at which the sun sets at West Point Lighthouse for any particular day can be modelled using the following equation where t(d) represents minutes since midnight and d is the number of days of the year.
a) Determine the maximum time of day for a sunset: _____________ [1]
b) Determine the period, including units: _______________ [1]
c) What is one possible day in which the sun would set at 6:25pm? [2]
Max = d + a = 1150 + 150 = 1300. 1300mins = 21hrs + 40mins = 9:40PM
