Hi can some one help Sandra is traveling 16 mph on her bicycle. After 2 hours, how far will she have traveled? A.
3 miles
B.
32 miles
C.
17 miles
D.
14 miles

32 miles

Step-by-step explanation:

B. 32 miles

Step-by-step explanation:

if sandra travels 16mph, the distance she travels in one hour, you simply have to multiply that by 2 because she travels for 2 hours.

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

graph of this function as shown below:

a. -0.3 > -0.33
