Answer 1

Given

$\bold{Gavyn \ can \ type \ 2200 \ words \ in \ 40 \ minutes.}$

$\implies \bold{Number \ of \ words \ typed \ in \ one \ minute}$

$= \dfrac{2200}{40}$

$\implies \boxed{\boxed{\bold{55 \ words \ in \ one \ minute}}}}$

$\bold{Stephen \ can \ type \ 3850 \ in \ 70 \ minutes.}$

$\implies \bold{Number \ of \ words \ typed \ in \ one \ minute}$

$= \dfrac{3850}{70}$

$\implies \boxed{\boxed{\bold{55 \ words \ in \ one \ minute}}}}$

$\bold{Richard \ can \ type \ 3000 \ words \ in \ 50 \ minutes.}$

$\implies \bold{Number \ of \ words \ typed \ in \ one \ minute}$

$= \dfrac{3000}{50}$

$\implies \boxed{\boxed{\bold{60 \ words \ in \ one \ minute}}}}$

$\boxed{\boxed{\bold{Therefore, \ Richard \ can \ type \ the \ fastest \ among \ the \ three}}}}}}$
