Question

A tank has a hole in it which leaks water at a rate of 335 ml per minute .If the tank is empty after 4 hours and 25 minutes ,how many litres of water can the tank hold?Give ur answer correct to 1 decimal place​

Answer 1

Change the length of time to minutes:

1 hour = 60 minutes.

4 hours x 60 = 240 minutes + 25 minutes = 265 minutes

Multiply leak rate by total minutes:

265 x 335 = 88,775 ml

Half the tank was 88,775 ml

Multiply by 2 to get the full tank amount:

88775 x 2 = 177,550 ml

Divide by 1000 to change to liters:

177,550 / 1000 = 177.55 liters

Answer to 1 decimal place = 177.6 Liters
