Question 7366
You've got the right formula but, since you are looking for "how long" you need the time.  So rewrite the formula so that time is on the left.

{{{Time = distance/speed}}} Now substitute the given values for distance (35 miles) and speed (55 mph).

{{{Time = 35 miles/55 mph}}}

{{{Time = 0.6363}}}hours.  Convert to minutes, multiply by 60 mins/hour.

{{{Time = 38.2}}} minutes.
