Answer:

2
(16)/(17) miles

Explanation:


(miles)/(minutes) =
(miles)/(minutes)


(1 1/4)/(8 1/2) =
(x)/(20)

1
(1)/(4) is the same as
(4)/(4) +
(1)/(4) (1 =
(4)/(4) )

8
(1)/(2) is the same as
(2)/(2) +
(2)/(2) +
(2)/(2) +
(2)/(2) +
(2)/(2) +
(2)/(2) +
(2)/(2) +
(2)/(2) +
(1)/(2) =
(17)/(2) (1 =
(2)/(2))


((5)/(4) )/((17)/(2) ) =
(x)/(20)


(17)/(2) x = 20 multiply both sides by
(2)/(17)


(2)/(17)
((17)/(2))x =
(2)/(17)
((20)/(1))

x =
(40)/(17)


(5)/(4)
((40)/(17)) = x


(50)/(17) or 2
(16)/(17)
