If exact, then #2.7358848# kilometers, so to #2# significant figures that is #2.7# kilometers.

So if the figure #1.7# miles is precise, then in kilometers it is:

#1.7 * 1.609344 = 2.7358848#

If the figure given is only accurate to #2# significant figures, then we should only quote the answer to #2# significant figures too.

So #1.7# miles is approximately #2.7# kilometers.
