Question

< Tank A initially contained 124 liters of water. It is then filled with more water, at a constant rate of 9 liters per minute. How many minutes have passed, m, when Tank A contains 151 liters How many minutes have passed, m, when Tank A contains 191.5 liters How many minutes have passed,y, when Tank A contains x liters

Answer 1

we get that the equation that models this situation is:

`L=9m+124`

where L is the number of liters and m the minutes. So we have that

`151=124+9m\rightarrow m=(151-124)/(9)=3`

so after 3 minutes the tank jas 151 liters

`191.5=124+9m\rightarrow m=(191.5-124)/(9)=7.5`

so after 7.5m the tanks has 191.5 liters

and for the last one we get

`x=9y+124\rightarrow y=(x-124)/(9)`
