A car is traveling 83.3 kilometers per hour. What is its speed in miles per minute? One kilometer = 0.62 miles.
Leya [2.2K]
Hi. 2fouls! :)

First convert the number from kilometer to miles:
83.3*0.62
=51.646 miles

Now to find the miles per minutes,divide the miles per hours by 60 (the amount of minutes in an hour.)

51.646/60
=0.860766667

The car is travelling at a speed of 0.860766667 miles/minute.

Hope this helps.

How many hydrogen atoms are in 5 molecules of isopropyl alcohol, c3h7o?
Oduvanchick [21]
1 molecule of C3H7O has 7 atoms of hydrogen (remember that the numbers to the right of each symbol ara subscripts and they indicate the number of atoms of that element in the molecular formula).

Then 5 molecules will have 5 * 7 atoms of hydrogen.

5 * 7 = 35.

Then the answer is that there are 35 atoms of hydrogen in 5 molecules of isopropyl alcohol, C3H7O
