The 17th hole at the famous St Andrews golf course is 420m in length. how long will it appear on a plan of course of scale 1:8000?

To find out how long the 17th hole at St Andrews golf course will appear on a plan of scale 1:8000, we can use the concept of scaling.

The scale 1:8000 means that one unit on the plan represents 8000 units in real life. In this case, let's assume that the unit on the plan is in meters. So, if we want to find out how long the 17th hole appears on the plan, we need to divide its actual length by the scaling factor.

The length of the 17th hole is given as 420 meters. Dividing this length by the scaling factor of 8000 will give us the length on the plan:

Length on plan = Actual length / Scaling factor
Length on plan = 420 meters / 8000
Length on plan ≈ 0.0525 meters

Therefore, the 17th hole at St Andrews golf course will appear as approximately 0.0525 meters long on a plan of scale 1:8000.

1/(8000*450) = 2.77*10^-7
