On a road james drives 250 miles per day . How many days d, must james travel to reach a distance of at least 1,300 miles

Number of days= 5.2 days

Step-by-step explanation:

Giving the following information:

Daily distance traveled= 250 miles

Total number of miles= 1,300 miles

To calculate the number of days to cover 1,300 miles, we need to use the following formula:

Number of days= total distance / daily distance traveled

Number of days= 1,300 / 250

Number of days= 5.2 days

the direct variation says that:

then the equation is of the form is given by:

            where k is the constant variation.

from the given table:

consider any value of x and m(x)=y

x = 2 and m(x)=y = 3

substitute these value in [1]; we have;

divide both sides by 2 we get;

⇒

check:

put x = -1 and m(x) = -1.5

substitute in the equation:

-1.5 = -1.5                   true

therefore, the function m(x) represents a direct variation
