Answer:
The answer is 192.78 inches
Step-by-step explanation:
An oval is formed by a rectangle with semicircles at each end. We can visualize this easily.
The length of the rectangle is 54 inches.
The width of the rectangle is 27 inches.
The perimeter of rectangle is =
=
= 162 inches
And because there are two semicircles, we can combine them to form a circle. So, perimeter of a circle is called a circumference.
The width of the rectangle forms the diameter, so its half will be the radius.
r =
The circumference is given by :
= inches
Now as the described oval shape is a complete figure without lines inside, we will subtract the width of both sides of the rectangle from the complete perimeter.
The complete perimeter is = inches
The inner edge perimeter will be = = 192.78 inches

the rate given is 345 ft/min
this means within 1 min distance is - 345 ft
we have to convert this speed to ft/h
1 hour is equivalent to 60 minutes
so if 60 minutes equals 1 hour
1 minute is equal to - 1/60 hr
so the distance within 1 minute is - 345 ft
since 1 min = 1/60 hr
distance within 1/60 hour = 345 ft
therefore distance in 1 hour =
answer is 20 700 ft/h
