Answer:
Mayra is running at a speed of 6.5 miles per hour.
Step-by-step explanation:
There are a few ways to solve this problem using different operations. First, you need to convert 3 and a quarter into a decimal. Since we know that a quarter is represented by 1/4, or 0.25, then we can combine this with Mayra's other 3 miles to get 3.25 miles. Also, one half is the equivalent of 1/2 or 0.5 of an hour. Since we know that 1/2 + 1/2 equals a whole, then if we take the distance that Mayra traveled in 0.5 of an hour and multiply it by 2, we would get her distance for the full hour: 3.25 x 2= 6.50. We can also solve be taking her original distance of 3.25 and dividing by the total time of 0.5: 3.25/0.5 = 6.50. Either operation will give us the same answer.
Mayra's speed in miles per hour is equal to 6.5 miles per hour.
Given the following data:
To calculate Mayra's speed in miles per hour:
Speed can be defined as the distance covered (traveled) by a physical object per unit of time.
Mathematically, speed is given by this formula;
[tex]Speed = \frac{distance}{time}[/tex]
Substituting the given parameters into the formula, we have;
[tex]Speed = \frac{\frac{13}{4} }{\frac{1}{2} } \\ \\ Speed =\frac{13}{4} \times 2\\ \\ Speed =\frac{13}{2}[/tex]
Speed = 6.5 miles per hour.
