The height, h meters, of the point P above ground level, at the time t hours after 1.00pm is given by;

h(t) = 62 + 60sin( (5t-1)pi / 2)

**Two questions to the information;**

i. Find the time, after 1.00pm, when P first reaches a height of 92 meters above ground level.

ii. Find the **number of minutes** during one rotation that P is at least 92 meters above ground level.

All help is much appreciated.
