Answer: The conversion factor between km and m is 1 km = 1000 m, and between hr and seconds, it is 1 hr = 3600 s. Let's first convert 9 km/hr to m/hr.
9 km/hr x (1000 m / 1 km) = 9000 m/hr
Then use the 2nd conversion factor to convert hr to seconds.
9000 m/hr x (1 hr / 3600 s) = 9000 / 3600 m/s = 5/2 m/s
