Answer: There are 28 countries that she can travel in 40 days.
Step-by-step explanation:
Since we have given that
Number of countries = 42
Number of days = 60
We need to find the number of countries in 40 days.
Since there is direct variation between number of days and number of countries.
So, our equation becomes,
[tex]\dfrac{42}{60}=\dfrac{x}{40}\\\\x=\dfrac{42\times 40}{60}\\\\x=\dfrac{1680}{60}\\\\x=28[/tex]
Hence, There are 28 countries that she can travel in 40 days.
