I really don't know how to attempt how to do this. Found 2 solutions by JimboP1977, richwmiller:Answer by JimboP1977(311) (Show Source):
You can put this solution on YOUR website! This formula is well worth storing in your memory if you can: distance/time = speed. Remember when using this formula to keep the measurement units you use the same eg if your speed is in mph then your distance must be in miles and time in hours.
If d=distance and t=time and s=speed. d/t=s
What do we want to find? We want to find t and we know d and s. So we need to rearrange the fomula to equal t.
times both sides by t gives divide both sides by s gives
Plug in the numbers and we are laughing! I shall leave you to do the last bit.
Let me know how you get on!

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.
