Speed = 600 m/sec.
=> 600/ 5 x 60,
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
2 multiply 3600/1000,
= 18 km/hr.
Then
= 2 x18/5 km/hr
= 7.2 km/hr.
=> 600/ 5 x 60,
= 2 m/sec.
Converting m/sec to km/hr (see important formulas section)
2 multiply 3600/1000,
= 18 km/hr.
Then
= 2 x18/5 km/hr
= 7.2 km/hr.

600/5 = 120.
120m per minute.
120 * 60min = 7200m.
1000m = 1 km.
7200/1000 = 7.2km per hour.
120m per minute.
120 * 60min = 7200m.
1000m = 1 km.
7200/1000 = 7.2km per hour.

Distance = 600m = 600/1000 km
= 0.6 km.
Time = 5mint = 5/60 hr = 1/12 hr.
Speed = Distance/time.
= (0.6)/1/12.
= 0.6×12.
=7.2
= 0.6 km.
Time = 5mint = 5/60 hr = 1/12 hr.
Speed = Distance/time.
= (0.6)/1/12.
= 0.6×12.
=7.2

Time = 5 min.
Distance = 600 meter.
Distance = 600/5 = 120m in one minute.
In hour = 120x60 = 7200m in one hour.
1km = 1000m.
7200m = 7.2m=>answer.
Distance = 600 meter.
Distance = 600/5 = 120m in one minute.
In hour = 120x60 = 7200m in one hour.
1km = 1000m.
7200m = 7.2m=>answer.

600m = 5 minutes, 120m = 1 minutes (600/5),
1 hour = 60 minutes,
7200m = 60 minutes (120*60),
1000m = 1 km.
7200m = 7.2 km.
1 hour = 60 minutes,
7200m = 60 minutes (120*60),
1000m = 1 km.
7200m = 7.2 km.

Changing kmph to mps.
1km = 1000m.
Minute = 60sec.
1000/60×60 = 5/18.
Changing opposite mps to kmph is 18/5.
1km = 1000m.
Minute = 60sec.
1000/60×60 = 5/18.
Changing opposite mps to kmph is 18/5.

1000 meter = 1 kilometer.
3600 seconds = 1 hour.
1000 meter/3600second=1 kilometer/1 hour.
5 meter/18 second = 1 kilometer/1 hour.
3600 seconds = 1 hour.
1000 meter/3600second=1 kilometer/1 hour.
5 meter/18 second = 1 kilometer/1 hour.
