Question

If a tank leaks 10 mL of fluid each hour, how long will it take to fill up a one-litre jar?

10 hours
1,000 hours
1 hour
100 hours

Answer 1

100 hours

Explanation:

To find the amount of liters in one hour, you divide 10 by 1000, which gives 0.01 liters each hour. From here, the 1 is in the hundredths place, so if you multiply by 100 hours, if will be at 1 liter.
