Figure please....

VITEEE Papers › Trignometry questions › Figure please....

A lighthouse, facing north, sends out a fan-shaped beam of light extending fron north-east to north-west. An observer on a steamer, sailing due west, first sees the light when he is 5 km awayfrom the lighthouse, and continues to see it for 30 x sqrt.2 minutes. What is the speed of the steamer...? Can anyone draw a figure for this ?

time= 30âˆš2 min.
d= 5âˆš2
v= d/t = 1/6 km/min.

Thanks. I took the light to be rotating from NE to NW. And I also took the boat to already be travelling in west direction.

So, this one's not that difficult I see. Just the figure matters
