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

step-by-step explanation:

when a number is between two straight lines it means the absolute value.

to find absolute value you need to know how many numbers is that number away from 0.

when finding absolute value the number will always come out positive

so absolute value of -3 is 3

absolute value of 3/2 is 3/2

absolute value of -2 is 2

absolute value of 3.5 is 3.5

absolute value of -1 is 1

now put these numbers in order:

a)   |-1|, |3/2|, |-2|, |-3|, |3.5|
