Three students, X, Y, and Z, climbed a vertical rope in a PE lesson. The table below shows their results.

Student	Weight in $N\text{N}$	Height climbed in $m\text{m}$	Work done in $J\text{J}$	Time taken in $s\text{s}$	Power output in $W\text{W}$
X	550	5.0	2750	6.0	458
Y		5.0	2500	5.0	500
Z	600	5.0	3000		375
