can you please check my work

19mm=? m ?=.19???

.017km=? cm ?=1700?

61500cm/min =? km/h ?=.615?

thank youuu!

.019 (missed a decimal space)

1700 is correct

The last one is a little trickier. First, figure out how many km per minute you are moving:

.615 km/minute

Since that is one minute and there are 60 minutes in an hour, multiply that by 60 to find out how fast you're going per hour:

.615*60 = 36.9

So 36.9 km/hr
