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
Hope this helps :)
Step-by-step explanation:
3n-7n-n = 15
5n = 15
n = 15 ÷ 5
n = 3
Sin(30)=ops/hyp=x/22
22*sin(30)=opposite
22*sin(60)=opposite
