Answer:

19.2 kg

Step-by-step explanation:

Amount of Bananas consumed in US per year = 5.77 million metric tons

Since 1 million = $10^{6}$ and 1 metric ton = 1000 kg, we can write:

Amount of Bananas consumed in US per year = $5.77 \times 10^{6}$ metric tons

Amount of Bananas consumed in US per year = $5.77 \times 10^{6} \times 1000 = 5.77 \times 10^{9}$ kg

Number of people in US = 301 million = $301 \times 10^{6}= 3.01 \times 10^{8}$

We have to find how many kilograms of bananas are consumed per person in 1 year in US. For this we have to divide the total amount of bananas eaten in US per year with total number of people in US, which will be:

$\frac{5.77 \times 10^{9}}{3.01 \times 10^{8}} \\\\ = 19.2$

This means, 19.2 kilograms of bananas are eaten in US per person in a year.
