Question 1

What is the difference between pace and speed?

Accepted Answer

Pace = time per distance (min/km). Speed = distance per time (km/h). 6 min/km = 10 km/h. Runners prefer pace.

Question 2

How do I convert pace to speed?

Accepted Answer

60 ÷ pace (min/km) = speed (km/h). 5 min/km = 12 km/h. 10 min/mile = 6 mph.

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.
