Answer:
8 hours 15 min
Step-by-step explanation:
Ronald’s 1 hour’s work = \frac{32}{6}=\frac{16}{3}\ pages
Pages typed in 6 hrs. = 32, Pages typed in 1 hr = \frac{32}{6}
Elan’s 1 hour’s work = 8 pages
1 hour’s work of the both = \frac{16}{3}+8 = \frac{40}{3}\ pages
∴ Required Time = \frac{110\times 3}{40} = \frac{33}{4}\ hours = 8\ hours\ 15\ minutes
Hope this helps
