Miles driven per hour is 60 miles per hour
Hours driven per mile is 0.01667 hours per mile
<em><u>Solution:</u></em>
Given that,
On a recent road trip, Mr. Yost drove 210 miles in 3 1/2 hours
Therefore,
Miles driven = 210 miles
To find: miles driven per hour and the hours driven per mile
<h3><u>Miles driven per hour</u></h3>Thus both the miles driven per hour and the hours driven per mile are found
Let's solve this problem. We know the equation of <span>the height of the ball that is:
</span>
<span>
Where x represents </span><span>the horizontal distance in yards the ball has traveled in the air. We know that a distance is always positive, so we conclude that x must be greater or equal than 0, so:
</span>
<span>
The horizontal plane represents the zero of the function, given that there is no possibility for the ball to get negative values, then
is also positive. Finally, from the graph, the appropriate domain is:
