Answer:
Step-by-step explanation:
This is a problem of conversion of units.
First of all you need to take the quantity the problem gives you and write it down with the units:
Then you need to find the conversion factor for the units you need to convert:
In this case you need to convert from meters (m) to kilometers (km) and from seconds (s) to hours (h), so you have the following conversion factors:
- To convert from meters (m) to kilometers (km):
-To convert from seconds (s) to hours (h):
Then you should put the conversion factors in the same expression, so:
Finally you multiply the numerators and the denominators and divide the results:
