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

It looks like there are some errors in your conversions. Let's go through each one and correct them:
1) 19mm to m: To convert millimeters to meters, you need to divide by 1000 since there are 1000 millimeters in a meter.
19mm ÷ 1000 = 0.019m (Corrected)
2) 0.017km to cm: To convert kilometers to centimeters, you need to multiply by 100,000 since there are 100,000 centimeters in a kilometer.
0.017km × 100,000 = 1,700cm (Corrected)
3) 61500cm/min to km/h: This requires a two-step conversion. First, convert centimeters per minute to kilometers per minute by dividing by 100,000 since there are 100,000 centimeters in a kilometer.
61500cm/min ÷ 100,000 = 0.615km/min
Then, convert kilometers per minute to kilometers per hour by multiplying by 60 since there are 60 minutes in an hour.
0.615km/min × 60 = 36.9km/h (Corrected)
So the corrected conversions are:
- 19mm = 0.019m
- 0.017km = 1700cm
- 61500cm/min = 36.9km/h
Please double-check your work with these corrections. Let me know if you have any further questions!
