Learning Goal: To practice Tactics Box 1.3 Making a unit conversion. One effective method of performing unit conversions begins by noticing that since, for example, I mile 1.609 km, the ratio of these two distances-including their units-is equal to one, so that 1 mile 1.609 km 1.600 km 1 mile. Such a ratio of values that is equal to one is called a conversion factor. The tactics described here show how to make a unit conversion using conversion factors. Use the fact that 1 inch = 2.54 cm and convert 39 inches into the equivalent length in ce Express your answer in centimeters.

I have a couple of follow up questions: 1) Is that 60k^ kgm^2/s, the SI unit for L 2) It wanted an expression as a function of time; so would it be L(t) = 60k, in which case it's 60k no matter what the value of t is? Hopefully, I'm getting across what I mean. Thank you.
