Answer: The running speed of Elena is 5 miles/hour and this can be determined by using the formula of speed.
Step-by-step explanation:
A circular running track 1/4 is a mile long.
Elena runs on this track, completing each lap in 1/20 of an hour.
Speed formula is used to determine the speed of Elena. The formula of speed is given by:
----- (1)
where S is the speed, D is the distance and T is the time taken by Elena to run a circle.
Now, put the value of distance D and time T in the equation (1).
Speed = 5 miles/hour
Therefore, the running speed of Elena is 5 miles/hour.

Answer:
If a rectangle's perimeter and area is the same, and the width is three, then the length would be 6.
Step-by-step explanation:
Let x miles/hr be the speed of the plane in still air and y miles/hr be the speed of the wind.
We have 10hr * (x + y)miles/hr = 880 miles
and 20 hr * (x - y)miles/hr = 880 miles.
=> (x + y) = 88 and (x - y) = 44.
Therefore 2x = 88 + 44 = 132 and x = 66.
The speed of the plane in still air is 66 miles per hour.
