The distance required to stop a car varies directly as the square of its speed. if 250 feet are required to stop a car traveling 60 miles per hour, how many feet are required to stop a car traveling 96miles per hour​

640 feet.

Step-by-step explanation:

Let d represent the distance required to stop and let s represent the speed of the car.

The distance required to stop varies directly as the square of its speed. In other words:

Where k is the constant of variation.

250 feet are required to stop a car traveling 60 miles per hour. Substitute:

Simplify and solve for k:

So, our equation is:

Then the distance required to stop a car traveling 96 miles per hour will be:

the solution is the point

step-by-step explanation:

we have

> equation a

> equation b

adds equation a and equation b

substitute the value of x in equation b to find the value of y

the solution is the point

step-by-step explanation:

a child is 12 years old, and his father is 32 years older. in how many years will the age of the father be 2 times the age of the child?
