Answer:

~65.45mph  (65.454545...mph)

Step-by-step explanation:

[tex]55(seconds) = 1 (miles)[/tex]

[tex]55(seconds) * 60 = 1 (miles) * 60[/tex]   ⇒    [tex]55(minutes) = 60 (miles)[/tex]

[tex]55(minutes) * 60 = 60 (miles) * 60[/tex]   ⇒  [tex]55(hours) = 3600 (miles)[/tex]

3600(miles)/55(hours ≈ 65.45mph
