E, there is no way to figure out the three individual lengths.

5.8
5.2

was the only possibility

E

Letâ€™s call the fragments a, b, c where a>b>c

(1) a + b =12

(2) b + c = 11

Therefore c â€“ a = 1

There are many solutions(6.1, 5.9, 5.1 or 6.3, 5.7, 5.3, etc), but Iâ€™ve plugged in and realised that a,b,c canâ€™t have any possible value. The only possible values have to fulfil the conditions above and be within certain ranges:

6<a<6.5
5.5<b<6
5<c<5.5
