A blue rope is three times as long as a red rope. A green rope is 5 times as long as the blue rope. If the total length lf the three ropes is 508.26 meters, what is the length of the blue rope?

1 answer

R = 1/3B

G = 5B

R + G + B = 508.26

Substitute 1/3B for R and 5B for G in the second equation and solve for B.
