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
