Can someone explain to me how to do this? I have no idea where to even start! Use dimensional analysis to find the number of cm/min in 5.8 m/hr.

Wait, what was your original question. Are you converting 560 mi/hr to cm/minute or the other way around?

5.8 metres * 1 hour * 100 cm 1 hour * 60 minutes * 1 metres

5.8 * 100 = 580 / 60= 9.67 cm/minute

Do the math and your answer will come out to cm/minute.

If your teacher is wants your answer in significant figures pay attention to how many places after the decimal you record your answer to.

Something that always helps me come up with conversion factors is this: Find out what's equal, so for example: \[1 \ hour = 60 \ minutes \] And then if I want to convert something from hours to minutes, I multiply like this in that equation: \[1 = \frac{ 60 \ minutes}{1 \ hour}\] So now I have a conversion factor, which is really equal to 1! Anything multiplied by 1 doesn't change, so similarly conversion factors don't change it either. So as an example, let's say I want to convert 3 hours to minutes? \[3 \ hours * 1 = 3 \ hours * \frac{ 60 \ minutes}{1 \ hour} \] \[ 3 \ \cancel{ hours} * \frac{ 60 \ minutes}{1 \cancel{ hour}} = 3*60 \ minutes = 180 \ minutes \]
