Engineers use the formula d=0.05r^2+1.1r to estimate the minimum stopping distance( d) in feet for a vehicle traveling r miles per hour if a car was traveling 50 mph what would be the distance it would take for the car to stop

The formula to estimate the minimum stopping distance( d) in feet for a vehicle traveling r miles per hour is given by:

Now we have to find the distance covered by the car while it was travelling at the rate of 50 miles per hour.

So in order to find that distance we have to plug the value of rate (r) as 50 miles per hour in the formula given to us.

Plugging r as 50 in the formula , we have

d=180 miles

The distance covered by the car for the car to stop, travelling at 50 miles per hour is 180 miles.

connie < felicia < stew

step-by-step explanation:

stew:

we need to find the slope

m = (y2-y1)/ (x2-x1)

    = (2650-795)/(10-3)

    = 1855/7

connie:

we need to find the slope

m = (y2-y1)/ (x2-x1)

we have two points (0,0) and (4,800)

m = (800-0)/(4-0)

  m = 800/4

felicia:

260 words per minute

200< 260 < 265
