The stopping distance on wet pavement at 20mph is about 60feet. The stopping distance at 30mph is 120feet. What would you estimate the stopping distance is at 40mph? Construct a formula

--- formula

The stopping distance at 40mph is 180ft

Step-by-step explanation:

Given

Solving (a): Construct a formula

Calculate the slope (m)

So, the equation is:

Open bracket

Hence, the formula to use is:

Solving (b): y, when x = 40

x= 3^y

step-by-step explanation:

the correct answer would be d because the slope is -2/2=1 and the y intercept is at 2 so that is the correction equation
