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
