The stopping distance, d ( in feet) for a van moving at a velocity (speed) v miles per hour is modeled by the equation: d = 0.04v + 1.1v
What is the stopping distance for a velocity of 10 miles per hour?
a. 10 ft
b. 7 ft
c. 15 ft
d. 13 ft

Note: The must be instead of .

Given:

The stopping distance, d ( in feet) for a van moving at a velocity (speed) v miles per hour is modeled by the equation:

To find:

The stopping distance for a velocity of 10 miles per hour.

Solution:

We have,

where, d is stopping distance and v is velocity.

Substitute v=10  in the given equation to find the stopping distance for a velocity of 10 miles per hour.

So, the stopping distance for a velocity of 10 miles per hour is 15 ft.

Therefore, the correct option is c.

the answer is b.
