Hint: These are the first letters of the words: W, O, B, H, D, F, C, N, H, D.
wat + erf + all = waterfall
ove + rbo + ard = overboard
ban + dst + and = bandstand
hai + rbr + ush = hairbrush
dif + fer + ent = different
fis + her + man = fisherman
con + duc + tor = conductor

Hint: Alex had been teaching 6 years longer than Blake.
Alex had been teaching 21 years.
Blake had been teaching 15 years.
Charlie had been teaching 7 years.
Alex and Blake had been teaching for a total of 36 years.
Charlie and Blake had been teaching for a total of 22 years.
Charlie and Alex had been teaching for a total of 28 years.
Let Alex = A, Blake = B and Charlie = C, then:
A + B = 36  C + B = 22  C + A = 28 
If we use  -  we have:
A - B = 6 
If we use  +  we have:
2A = 42 A = 21
By  B = 15. By  C = 7.
