The distance traveled by the driver during her reaction time based on her speed was 44 feet.
<h3>How far did the driver get during her reaction time?</h3>
find the speed in feet per second to be:
= (40 x 5,280 feet per hour) / Number of seconds in an hour
= 211,200 / 3,600
= 58.67 feet per second
With a reaction speed of 3/4 seconds, the distance traveled is:
= 58.67 x 3/4
= 44 feet
Full question is:
The driver of a car traveling at a speed of 40 miles per hour had to stop the car quickly. Using the driver's speed in feet per second, how far did her car travel during her reaction time of 3/4 of a second?Round your answer to two decimal places

Try 21 if its wrong sorry im not very smart
You got it, both the x’s interest there

Answer:
A. 1, 287 ways
B. 154,440 ways
Step-by-step explanation:
A. We want to choose 5 objects from a total 13, without considering the order in which they are chosen.
The correct way to do this is by using the combination formula since order is not considered;
Thus we have ; 13 C 5 read as 13 combination 5;
Mathematically, n C r is ; n!/(n-r)!r!
Thus, we have ;
13!/(13-8)!8! = 13!/5!8! = 1,287 ways
B. By considering order, we shall be using the permutation formula;
Mathematically n P r = n!/(n-r)!
Read as n permutation r;
Using the numbers involved, we have ; 13 P 5
= 13!/(13-5)! = 13!/8! = 154,440 ways
