An hour glass pours sand at a rate of 10 grams every hour. If I measured 4 lbs of sand, how many hours did it take to pour?

Answer 1

4 lbs is 1814.37 grames so the answer is 3

Step-by-step explanation:

1814.37 ÷ 10 = 181.437

so now to find how many hours.

181.437 ÷ 60 =3.02395 or you can just say 3 hours

(we divide by 60 Because there are 60 minutes in an hour)
