Change the words into formulas:
60miles per hour = 60miles/60 minutes
60 miles/60 minutes = 320 miles/ x minutes
Now solve for x:
multiply both sides by x and you get
60x/60 = 320
60x/60 = x (the 60s cancel out) = 320
there are 60 minutes in an hour
320 minutes = 5 hours (300 minutes) and 20 minutes

320 divided by 60 is the number of hours, which works out to 5.333 hours. One-third of an hour is 20 minutes, so the final answer is 5 hours and 20 minutes to travel 320 miles.

320 miles divided by 60 miles per hour = 5.3333 or about 5 hours and 20 minutes

320 divided by 60 = 5.3333
so it takes about 5 hours and 20 minutes
it's not 5 hours and 33.33 minutes because the divison gives you an answer in units of hours. .33 percent of an hour is about 20 mins....

320/60 will give you the hours. convert hours into minutes by the conversion factor of 60 min in an hour then you will have the minutes

remember, rate times time equals distance.
so the equation would be:
60t = 320
t= 320/60
t = 16/3 which is 5 1/3 hours
