In reducing one's speed from 70 mph to 50 mph, how much of a percentage decrease in stopping distance is realized (to the nearest percent)?

we are given relation between speed and distance

distance ( when speed =70mph) is

=328feet

so,

distance ( when speed =50mph) is

=183feet

so,

now, we can find percentage in decrease

now, we can plug values

%...........Answer

answer: the distance

step-by-step explanation:

to calculate the distance d of a line segment with endpoints (x1, y1) and (x2, y2) use the formula d (x2 x1)2 (y2 y1)2. to calculate the midpoint of a line segment with endpoints (x1, y1) and (x2, y2) use the formula
