Question

A blue rope in Garret's camping backpack is 6 yards long. The blue rope is 3 time as long as a red rope. A yellow rope is 2 feet 7 inches shorter than the red rope. What is the difference in length between the blue rope and the yellow rope.

?ft
?in

Answer 1

175 inches, 14.58 ft

Explanation:

Length of blue rope = 6 yards

also Length of blue rope = length of red rope * 3

=> 6 yards = length of red rope * 3

=> length of red rope = 6/3 = 2 yards

____________________________________

length of yellow rope = 2feet 7 inches shorter than red rope

1 yard = 36 inch

length of red rope in inches = 2 *36 = 72 inches

1 feet = 12 inches

difference of yellow and red rope in inches = 12* 2 + 7 = 31

length of yellow rope in inches = 72 inches -(12* 2 + 7 )= 72-31 = 41 inches

length of blue rope in inches = 36*6 = 216 inches

difference in length between the blue rope and the yellow rope = 216 - 41

= 175 inches

difference in length between the blue rope and the yellow rope in feet = 175/12 = 14.58 ft
