ship s travels at 24 kmh-1 anticlockwise along the arc of a circle, keeping 5n2km from the lighthouse, L.
find , in radians, the angle that the line ls has turned through in 26 minutes

right.. 24km/h is 04km/min
0.4 x 26 = 10.4
using the fast that r x theta radians is the perimeter of the arc.
10.4/5n2 = the answer in radians.
No idea what 5n2 means though, i think you made a type possibly?
I hope this helps, I have my C2 tomorrow aswell. Ahh.
