At 2:00pm a ship is at a position P from where a light house L is 12km away on a bearing of 320°.At 4:00pm, the ship is at a position Q from where the light house is now on a bearing of 035°. Given that the ship is travelling due West, find by calculation: i)how far the lighthouse is from
ii)the speed of the ship
iii)the closest distance of the ship from light house
iv)the light house, point Qand point Pwere noted to be along the circumference of a circular field. Find the distance of p from centre of the field.

Simplify the expression. -2/5(10+15m-20n)
