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 |

When we convert km/hr to m/s it's 18/5 and when we convert m/s to km/he it's 5/18.

2*60(min)*60(hr)/1000.
Then we get the answer 36/10(or)18/5*2.
Answer=7.2km/hr.

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

600/5=120/min,
1min=120m,
60min=60*120m=7200,
1000m=1km.
So, 7200m/1000m=7.2/hr.
1min=120m,
60min=60*120m=7200,
1000m=1km.
So, 7200m/1000m=7.2/hr.

Guy's those who don't know how 18 comes.
Here is the answer 3.6 multiply 5=18?

S = d/t.
600m = 0.6km.
5minutes = 5/60 = 0.083hr,
S = 0.6/0.083,
= 7.2km/hr.
600m = 0.6km.
5minutes = 5/60 = 0.083hr,
S = 0.6/0.083,
= 7.2km/hr.

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

s = d/t.
s = 600m/5min.
120m/1min.
60*120/60*1.
7200m/60min .
7.2km/1hr.
s = 600m/5min.
120m/1min.
60*120/60*1.
7200m/60min .
7.2km/1hr.
