Answer:
Explanation:
Let all the measurements be in same unit.
200 cm = 2 m
2000 mm = 2 m
Let distance jumped by Jack = x m
Distance jumped by Jerzy = x + 2
Distance jumped by Abdullah = (x+ 2) + 2 = x + 4
Total = 12.69 m
x + x +2 +x +4 = 12.69
x +x + x + 2 + 4 = 12.69
3x + 6 = 12.69
3x = 12.69 - 6
3x = 6.69
x = 6.69/3
x = 2.23 m
distance jumped by Jack =2.23m
Distance jumped by Jerzy = 2.23 + 2 = 4.23 m
Distance jumped by Abdullah = 2.23 + 4 = 6.23 m
