Final answer:
The velocity of 5.655 X 10° um/sec is equivalent to approximately 0.02038 km/hr, which is quite slow.
Step-by-step explanation:
The velocity you provided, 5.655 X 10° um/sec, is actually quite slow. To convert this velocity into kilometers per hour, we can use the fact that 1 kilometer is equal to 10^12 micrometers (um).
First, let's convert the velocity from micrometers per second (um/sec) to kilometers per hour (km/hr). We will need to multiply the velocity by a conversion factor.
Conversion factor = (1 kilometer / 10^12 micrometers) * (3600 seconds / 1 hour)
Using this conversion factor, we can calculate:
(5.655 X 10° um/sec) * (1 kilometer / 10^12 micrometers) * (3600 seconds / 1 hour) = 0.02038 km/hr
Therefore, your velocity of 5.655 X 10° um/sec is equivalent to approximately 0.02038 km/hr.
