Hello!

Since we know how much they walked in 4/9 of an hour, we will divide 4/5 by 4/9 to get 4/9 to one.

[tex] \frac{4}{5} [/tex]÷[tex] \frac{4}{9} [/tex]=[tex] \frac{36}{20} = \frac{9}{5} [/tex]

They went 1 4/5 mph or 1.8 mph.

I hope this helps!
The Baldwin family walked  1.8 miles per hour, that is the unit rate :)
