seems like the main concept being tested here is unit conversion.
First, let's look at converting kilometers to meters. In the metric system, the prefix "kilo" means 1000. So,
1 kilometer = 1000 meters.
Then, let's look at converting from hours to seconds. As you may know, there are 60 minutes in an hour, and 60 seconds in a minute. So, in 1 hour there are
1 hour*(60 minutes/hour)*(60 seconds/minute) = 3600 seconds.
So, we can use these unit conversion factors to solve your question. Let's convert the units!
9 km/hr = 9 km/hr * (1000 m/km) * (1 hr/ 3600 sec) = 2.5 m/s
Hope this helps!
