Let x represent number of hours after noon.
We have been given that Sara starts at noon and walks at a speed of 4 miles per hour. So distance covered by Sara in x hours would be .
We are also told that Eddie leaves the same place an hour later. This means that Sara will be 4 miles ahead of Eddie as Sara will travel 4 miles in 1 hour.
As Eddie walks in the same direction at a speed of 5 miles per hour. So distance covered by Eddie in x hours would be .
Total distance covered by Sara when Eddie will start would be .
Now we will equate distance covered by both in x hours as:
Let us solve for x.
Since x represents number of hours after noon, so 4 represents 4 hours after noon.
Therefore, Eddie will catch up with Sara at 4:00 pm and option D is the correct choice.
Answer:
in radian <em>measure</em>
<em>theta=</em><em>length </em><em>of </em><em>arc </em><em>/</em><em>radius </em>
<em>so </em><em>a</em><em>=</em><em>l/</em><em>r</em>
<em>a</em><em>=</em><em>5</em><em>6</em><em>/</em><em>7</em><em>0</em>
<em>a</em><em>=</em><em>4</em><em>/</em><em>5</em>
Step-by-step explanation:
a= theta angle in radian
4000 * .02= 80. 80 * 2.5= 200. 2.5 years.
Solve the literal equation 2xy - xz = 4 for x
x = 4/(2y-z)
y =/ z/2
