Step-by-step explanation:
Velocity = Displacement/Time
a) Velocity in m/s = 3600m/6s
= 600m/s
b) (Converting m into km)
1000m = 1km
3600m = ?
3600/1000 = 3.6km
(Converting secs to hours)
1mins = 60secs
60mins = ?
60 * 60 = 3600 secs
This means there are 3600 secs in 1 hour
3600secs = 1hour
6.0 secs = ?
6.0/3600 = 0.00167 hours (approximately)
Velocity in km/h = 3.6km/0.00167h
= 2155.69km/h (approximately)
In summary...
a) 600m/s
b) 2155.69km/h
