Answer:
The distance between Harry’s home and his office? is 15 miles.
Step-by-step explanation:
The speed, distance time formula is:
Given:
Speed (<em>s</em>) = 30 miles/hour
Then the relation between distance and time is:
If Speed was 60 miles/hour the time taken is 
hours.
Then the relation between distance and time is:
Use the value of <em>d</em> = 30t in (ii)
<em />
<em />
Determine the distance as follows:
Thus, the distance between Harry’s home and his office? is 15 miles.
The answer is A. for this, you have to set up a system of equations. the first one will be the area equation. since you know area=length x width, your equation will be LxW=50. the next equation is L=2W, since the length is two times the width. then, plug in 2W for the L in the other equation and you get 2W^2=50. divide by 2 and get W^2=25. square root both sides and you get W=5. plug back into the other equation to find L=10. Then, add the sides of the rectangle for the perimeter. 10+5+10+5=30.
