Derivation
- ├── 01Given
distance = 5 km, time = 0h 25m 0s - ├── 02Total time in seconds
0×3600 + 25×60 + 0 = 1500 - ├── 03Formula
pace (s/km) = total seconds / distance - ├── 04Substitute
1500 / 5 - ├── 05Pace5:00 /km
- ├── 06Formula
speed (km/h) = distance / (seconds / 3600) - └── 07Speed5 / (1500/3600) = 12.00 km/h
Pheidippides ran ~40 km from Marathon to Athens in 490 BCE to announce victory — then died. The modern 42.195 km distance was fixed at the 1908 London Olympics so the royal family could watch the finish.
