To determine how much will it take to clean a 120ft driveway considering that it took him 2hs to clear 10ft and that the cleaning rate is constant, you can use cross multiplication:
10ft______2hs
120ft_____xhs
If the cleaning rate is the same, then the ratios between both are the same:
From this expression, you can determine the time by multiplying both sides of the equal sign by 120
It will take him 24 hours to clear the 120ft driveway.
The preferred choice would be a line graph (drawn in the figure attached) for displaying the data.
Why a line graph is the preferred option here?
- For displaying the data of David's family's grocery bills for the past 10 weeks, a line graph is the most preferable choice since it would display the data's trend for us. This is similar to how we would notice times when there were huge costs.
- Another reason for choosing a line graph is that it is very easy to comprehend. It is simple to observe how the data are related and how they have changed.
