1.1. A seagull sits on the surface of the sea and moves up and down as waves pass.

Its height, h metres, above its position in calm water is modelled by the function$h=\frac{2}{5}sin(180t)^{\circ}$where $t$ is the time in seconds afer timing commenced.

Find the first time the seagull is 0.3 metres above its calm water position.

Give your answer to 2 decimal places.

1.2. How many times in the first minute after timing commences is the seagull 0.3 metres above its calm water position?
