3Minute Rule
Distance Traveled in 3 mins (Yds) = Speed (kts) * 100

6Minute Rule
Distance traveled in 6 mins (nm) = Speed (kts) / 10

1000 yds in nm
1000 yds = 1/2 nm

At 5 knots I'll travel ____ yds in 3 mins and ____ yds in 6 mins
 5 kts = 500 yds in 3 mins
 5 kts = 1000 yds in 6 mins

At 10 kts I'll travel ____ yds in 3 mins and _____ yds in 6 mins
 10 kts = 1000 yds in 3 mins
 10 kts = 2000 yds (1 nm) in 6 mins

At 20 kts I'll travel __ yds in 3 mins and __ yds in 6 mins
 20 kts = 2000 yds in 3 mins
 20 kts = 4000 yds (2nm) in 6 mins

Radian Rule
Angle to object / 60, * by distance from it = CPA distance
