The time taken for her trip is 3 hours.
<h3>Given that</h3>Koto’s average velocity along her route was 4. 5 m/s.
She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west.
<h3>We have to determine</h3>What was the time of her trip?
<h3>According to the question</h3>She started at her house and traveled 15,000 meters north, 5,000 meters east, 20,000 meters south, and then 5,000 meters west.
<h3 /><h3>The calculation of such a trip of Koto can be done by applying the known formula of Time when the Speed is multiplied by Distance to compute the actual time of the trip.</h3>The formula to calculate the time for her trip is;
- Using the formula above, the commute in each direction is added as 45000 meters or 45 kilometers.
- If Koto's average speed is 4.5 meters per second, then she travels roughly 270 meters in one minute.
Substitute all the values in the formula;
Converting minutes into hours,
Hence, the time taken for her trip is 3 hours.

Answer: Option A is correct that is
Explanation:
we will substitute the values of n in given expression
when substituting n=1 we get in =
when n=2 we get
when n =3 we get ;3 factorial that is 3! = 3 *2*1 = 6
when n=4 we get ;4! = 4*3*2*1 = 24
Note: factorial means the product of the terms getting multiplied till 1
suppose n! will be equal to n(n-1)(n-2)(n-3).......1
