Elena's running speed is 5 miles/hour
Explanation:
The speed is defined as the covered distance per unit time
In the problem, we have:
The distance covered is the length (circumference) of the circular track which is given as of a mile.
We are also given that she completes each lap (she completes of a mile) in of an hour
To get her speed, we will divide the distance covered by the time taken to cover this distance
This is done as follows:
speed = miles/hour
This means that:
Elena can run 5 miles each hour

Answer:
D. -4027
Step-by-step explanation:
After the first two, the integers can be paired so that each pair has a sum of zero.
-2014 +(-2013) +(-2012) + ... (-1) +0 +1 + ... +2012
= -2014 -2013 +(-2012 +2012) +(-2011 +2011) + ... +(-1 +1) +(0)
= -4027 + 0 +0 +0 + ... +0
= -4027
24 of the 720 numbers have the numbers 1, 2 and 3 in that order
<h3>How to determine the number of arrangements?</h3>
The digits are given as:
1, 2, 3, 4, 5, and 6
For 1, 2 and 3 to come in that order, then the three numbers must be treated as a digit
So, we have:
(123), 4, 5, and 6
Now, there are 4 digits.
The number of arrangements is then calculated as:
Arrangements = 4!
Expand
Arrangements = 4 * 3 * 2 * 1
Evaluate
Arrangements = 24
Hence, 24 of the 720 numbers have the numbers 1, 2 and 3 in that order
