Imagine the water is leaking from a container, at a rate of 1.2 ml/hour. if this rate does not change, how many liters of water will be lost in a week?

If you round the days hours to 24 then multiply 7 you get 168, and then if you multiply 1.2 you would get 201.6
 so the answer would be 201.6 ml an hour

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.

Im here for points, sorry i dont have the answer ; /
