Question 244155
"You are traveling on the highway at an average speed of 55 miles per hour. How long will it take you to drive 66 miles?"
What do you know and what do you want to know?
You know the speed you are traveling and you know the distance to travel. 
And you want to know time (how long) for the trip. 
What formula uses speed(rate) and  distance  and time?
rate * time =distance
r*t=d
or
d=r*t
so solving for time
t=d/r
or
d/r=t
66/55 hours =t
6/5 hours=t
1 1/5 hours.
1 1/5 hour= 1 1/5*60=72 minutes
1/5 of an hour is 12 minutes
72 minutes or 1.2 hours
The question doesn't limit you to hours so either 72 minutes or 1 hour 12 minutes or 1.2 hours should be acceptable.
