Answer:

If you need a simplified fraction then 
(1/5) / 4.5 = 2 / m....1/5 mile to 4.5 minutes = 2 miles to m minutes
cross multiply
(1/5)(m) = (2)(4.5)
1/5m = 9
m = 9 * 5/1
m = 45 minutes <===
There is not a given equation nor ordered pair, so it is impossible to answer this question. I apologise.
