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.

Facts about Multiplication
The answer of the multiplication is called the product.
2. The product of any number multiplied by a ‘zero’ is zero.
Example: Think — If each child gets ‘zero’ sweets, how many sweets will 4 children get?
4 times 0 sweets or 4 × 0 = 0
3. The product of any number multiplied by ‘one’ is equal to the number itself.
Example: Think — If every child gets ‘1’ sweet, how many sweets are needed for 8 children?
1 child → 1 sweet
8 children → 8 times 1 sweet
8 × 1 sweet = 8 sweets
Product is equal to the number itself.
and I will let you put your own opinions but there is some facts
