Answer:
See below.
Explanation:
Develop conversions factors (such as 1km/1000m) as needed to convert the units. E.g., since there are 3600 seconds in an hour (60s*60m), we can write either 3600s/1h or 1h/3600s. Both are valid since in both cases the denominator and numerator are equivalent (and thus numerically equivalent to 1, even though the actual value is not 1 due to the unit change. Mathematically, is is still "1."
2m/s= km/h
1km = 1000m, or 1km/1000m
1h = 3600s, or 3600s/1h
(2m/s)*(1km/1000m)*(3600s/1h) = (2km/1000s)*(3600s/1h)= 7.2 km/h
9m/s= km/s
1km = 1000m, or 1km/1000m
(9m/s)*(1km/1000m)= 0.009km/s
36km/h= m/s
1km = 1000m, or 1000m/1km
1h = 3600s, or 1h/3600s
(36km/h)(1000m/1km)(1h/3600s) = 10m/s
108km/h= m/s
1km = 1000m, or 1000m/1km
1h = 3600s, or 1h/3600s
(108km/h)(1000m/km)(1h/3600s)= 30m/s
