| 5 x 60 |
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
| = | |
2 x | 18 | |
km/hr |

600 meters in 300 seconds;
100 meters in 50 seconds;
1000 meters in 500 seconds (8,33 minutes):
60 divided by 8,33 = 7,4 kmh.
100 meters in 50 seconds;
1000 meters in 500 seconds (8,33 minutes):
60 divided by 8,33 = 7,4 kmh.

Distance = 600 m = 0.6 km.
Time = 5 minutes = 5/60 = 1/12 hour.
Speed = Distance/Time.
= 0.6 ÷ (1/12),
= 0.6 × 12,
= 7.2 km/h.
Time = 5 minutes = 5/60 = 1/12 hour.
Speed = Distance/Time.
= 0.6 ÷ (1/12),
= 0.6 × 12,
= 7.2 km/h.

1km/hr=(1ooo/3600)m/s=(5/18)m/s
for converting m/s into km/hr 18/5 is required to use
for converting m/s into km/hr 18/5 is required to use
