Final answer:
To convert 9.05 um/s to km/hr, you multiply by the conversion factors for micrometers to kilometers and seconds to hours, resulting in 0.03258 km/hr.
Step-by-step explanation:
To convert 9.05 um/s (micrometers per second) to km/hr (kilometers per hour), we need to follow two conversion steps. First, we convert micrometers to kilometers, and then seconds to hours.
1 micrometer (um) is equal to 1 x 10^-6 kilometers (km), and 1 second is equal to 1/3600 hours (since there are 3600 seconds in one hour).
So, converting 9.05 um to km: 9.05 um * 1 x 10^-6 km/um = 9.05 x 10^-6 km.
Now, converting seconds to hours: 9.05 x 10^-6 km/s * 3600 s/hr = 0.03258 km/hr.
Therefore, the converted speed is 0.03258 km/hr.
