| Speed = |  |
600 |  m/sec. |
| 5 x 60 |
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
| = | |
2 x | 18 | |
km/hr |
| 5 |
= 7.2 km/hr.

Be cool for 5min 600m, so for 1 min 600/50 = 120m.
For 60min 60*120 = 7200m.
For 60min 60*120 = 7200m.

The speed is 600 m/5 min.
So, 5 min = 600 meters.
(1 hour = 12*5 min = 60 mins).
5min*12 = 600m*12.
60 minutes = 7200 meters.
So, 1 hour = 7000 m + 200 m.
1 hour = 7 km + 200 m.
= 7.2 km.
So, 5 min = 600 meters.
(1 hour = 12*5 min = 60 mins).
5min*12 = 600m*12.
60 minutes = 7200 meters.
So, 1 hour = 7000 m + 200 m.
1 hour = 7 km + 200 m.
= 7.2 km.

In 5 mins 600 meter.
In 1 mins 600/5 = 120 meter.
In 60 mins (1hr) 120*60 meter = 7200 meter.
In 1 hr 7.2 km.
i.e 7.2 km/hr.
In 1 mins 600/5 = 120 meter.
In 60 mins (1hr) 120*60 meter = 7200 meter.
In 1 hr 7.2 km.
i.e 7.2 km/hr.

In 5 minutes the person crosses 600 meter.
In 1 minute the person crosses 600/5 meter.
In 60 minutes the person crosses (600*60)/5 = 7200 meter = 7.2 km.
In 1 minute the person crosses 600/5 meter.
In 60 minutes the person crosses (600*60)/5 = 7200 meter = 7.2 km.

What's that conversion formula come from the real real formula was 1000/(60*60)?

Why don't we use the no 12 or 16 instead of 18?
