A rectangular field is twice as long as it is wide.
A golf cart traveling at 12 miles per hour takes 7.5 minutes to travel the perimeter of the field what is the length (in miles) of the field ?
:
Find out how far the cart goes in 7.5 min: 12 * = 1.5 miles
:
Perimeter equation
2L + 2W = 1.5
:
"A rectangular field is twice as long as it is wide."
L = 2W
:
Replace L with 2W in the perimeter equation, find W
2(2W) + 2W = 1.5
4W + 2W = 1.5
6W = 1.5
W =
W = .25 mi is the width
then
2(.25) = .5 mi is the length
:
:
Check 2(.5) + 2(.25) = 1.5
