Nana76 [90]

We have that for the Question "In the same year, the average finishing <em>time</em> for U.S. women was 4 <u>hours </u>and 41 <em>minutes</em>. What was the average female speed in miles per <em>hour</em>?" it can be said that

The average female speed in miles per hour

V_a=\frac{D}{4.683hours}

From the question we are told

In the same year, the <u>average</u> finishing <em>time</em> for U.S. women was 4 <u>hours </u>and 41 <em>minutes</em>. What was the average female speed in <u>miles</u> per <em>hour</em>?

<h3>Average speed </h3>

This is defined as the collective <u>mean</u> of different travel <em>intervals </em>

Generally the equation for Speed   is mathematically given as

V=\frac{Distance}{Time}

Therefore

For  4 <u>hours </u>and 41 <em>minutes=4.683hours</em>

This travels time was <em>obtained </em>over a  series of distance

<em>Hence</em>

<em>Distance D</em>

The average female <em>speed</em> in miles per hour

V_a=\frac{D}{4.683hours}
