Question

Which is faster?

213 miles/second or 4283 millimeters/hour

This is what I have so far. Is it correct?

213 mil/ 1 sec x 60 sec/1 min=12,780 mil/ 1 min x 60 min / 1 hr=766,800 mil/hr

Answer 1

Could I help you?

Answer 2

Yes, I know this isn't the right answer now, but I'm not sure what I'm doing wrong.

Answer 3

I first tried to convert the seconds to hours.

Then I tried to convert the miles to cm, but I got a huge wrong number.

Answer 4

This was my final answer

213 ml/ sec x 60 sec/ 1 min = 213x60 ml / 1 min x 60 min / 1 hr = 213 x 60 x 60 ml / hr = 766,800 mi / hr

766,800 ml / hr x 160934 cen / 1 ml = 766,800 x 160934 / hr = 123404191200 / 1 hr

Answer 7

Great!

The idea behind such problems is that you convert the unit of one quantity \ amount to the other unit of the other quantity(s)

Answer 8

I realized one mistake. I was using cm instead of mm.

Answer 9

213 ml/ sec x 60 sec/ 1 min = 213x60 ml / 1 min x 60 min / 1 hr = 213 x 60 x 60 ml / hr = 766,800 mi / hr

766,800 ml / hr x 1 609 344 mm / 1 ml = 766,800 x1 609 344 / hr = ???

I have this now
