Three boys recorded their standing broad jump distances. Marcus jumped 6 cm further than Henry. Eddie jumped 0.12 m further than Marcus. The three boys jumped a total of 5.19 m. How far did Eddie jump?
Let X be Henry's jump distance in cm.
Marcus jumped 6+X cm.
Eddie jumped 0.12+6+X cm.
The three boys jumped X+(6+X)+(0.12+6+X) cm=5.19m.
Thus, 3X+12.12=519.
Thus, 3X=519-12.12=506.88 cm.
Thus, X=506.88/3=<<506.88/3=168.96>>168.96 cm.
Thus, Eddie jumped 6+168.96+6+0.12=<<6+168.96+6+0.12=181.08>>181.08 cm. Answer: \boxed{181.08}.
