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

Answer:
The area = 30 units²
Step-by-step explanation:
∵ A (-4 , 1) and (2 , 1)
∴ AB is a horizontal segment (same y-coordinates)
∴ AB = 2 - -4 = 6 units
∵ B (2 , 1) and C (2 , -5)
∴ BC is a vertical segment (same x-coordinates)
∴ AB ⊥ BC
∴ BC = 1 - -5 = 6 units
∵ A (-4 , 1) and D (-4 , -3)
∴ AD is a vertical segment
∴ AD ⊥ AB
∴ AD // BC
∴ AD = 1 - -3 = 4 units
∴ ABCD is trapezium with parallel bases AD , BC and height AB
∵
∴ units²
Given :
Cost of our meal = $3.45 .
Cost of friend's meal = $3.90 .
We pay $10 bill for both the thing.
To Find :
How much change do you receive.
Solution :
Total cost of meal = $3.45 + $3.90 = $7.35 .
Now, amount of change received is :
Change = Total amount - Price of meal
Change = $10 - $7.35
Change = $2.65
Hence, this is the required solution.
