Kenny lives $1 1/4m$ from school

First, let miles $=m$

So we can say:

Lucas lives $5/8m$ from school

Therefore:

Kenny lives $2xx5/8m$ from school

Now we can apply the operation in Kenny's expression:

$2xx5/8m$

$= (2xx5)/8m$

$=10/8m$

This fraction can then be simplified:

$10/8m$

$=(10÷2)/(8÷2)m$

$=5/4m$

It is normally preferred to write improper fractions as mixed numbers, so:

$5/4m$

$=4/4m+1/4m$

$=1 1/4m$
