Question 1

What is a good swimming pace?

Accepted Answer

Beginner: 3-4 min/100m. Intermediate: 2-2:30/100m. Advanced: 1:30-2:00/100m. Olympic: <55s/100m (freestyle).

Question 2

How do I calculate swim pace?

Accepted Answer

Total time ÷ distance (in 100m units). 30 min for 1500m = 2:00/100m. Pools are usually 25m or 50m.

Question 3

What's the fastest speed possible?

Accepted Answer

The speed of light (299,792,458 m/s or about 670 million mph) is the universal speed limit. Nothing with mass can reach it.

Question 4

Why do pilots and sailors use knots?

Accepted Answer

One knot = one nautical mile per hour. Nautical miles relate directly to Earth's latitude (1 nm = 1 minute of latitude), simplifying navigation.
