The distance between Pittsburgh and Cleveland is 200 miles
<u>Solution:</u>
Given that,
Plane travels from Pittsburgh to Cleveland in 2 hours
Average speed of plane = 100 miles per hour
<em><u>To find:</u></em> Distance between these two cities
<em><u>The relation between speed distance and time is given as:</u></em>
On rearranging the above formula, we get
Distance between these two cities =
Thus both the cities are 200 miles apart
Area of a square 300 meaning the length times the width is 300.
And it’s a 1 to 3 ratio.
So I found that 30 times 10 is 300 and that is a 3-1 ratio.
The length is the bigger one so that would be 30, meaning the width is 10.
To find the perimeter, add all of the sides. This is a rectangle so the parallel sides are equal to one another. So the length of one side is 30. The length of the parallel side is 30. The width of one side is 10 and the width of its parallel side is 10. So… 30+30+10+10=80
