Answer:
the total minutes taken together is 26.25 minutes
Step-by-step explanation:
The computation of the number of minutes that required to fill the tank together is shown below:
[tex]\frac{1}{45} + \frac{1}{63} = \frac{1}{x}\\\\\frac{7 + 5 }{315} = \frac{1}{x} \\\\\frac{12}{315} = \frac{1}{x} \\\\12x = 315\\x = 26.25[/tex]minutes
Hence, the total minutes taken together is 26.25 minutes
