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.

Answer:
14, 15, 16
Step-by-step explanation:
Let integers equal:
x, x + 1, x + 2
2x = 12 + (x + 2)
2x = 12 + x + 2
2x = 14 + x
2x - x = 14
x = 14
x = 14
x + 1 = 14 + 1 = 15
x + 2 = 14 + 2 = 16
