Answer:
[tex]4.9*10^5[/tex] times
Step-by-step explanation:
For this, we need to divide the volume of atlantic with volume of Mississippi.
Remember the rules of dividing scientific notation numbers:
[tex]\frac{a*10^b}{z*10^y}\\=(\frac{a}{z})*10^{b-y}[/tex]
Now, we do for this problem:
[tex]\frac{3.1*10^{17}}{6.3*10^{11}}\\=(\frac{3.1}{6.3})*10^{17-11}\\=0.49*10^{6}\\=4.9*10^5[/tex]
Thus, mississippi can flow 4.9 * 10^5 times in Atlantic.
