Answer:

5.2 hours, or 5 hours 12 minutes

Step-by-step explanation:

The distance is the same in both cases.  Since distance = rate (time),

time = distance / (rate).

Here, (6 hr)(52 mph) = (time)(60 mph, or

               312 mi         = (60 mph)(time), which gives us

(time) = (312 mi) / (60 mph) = 5.2 hours, or 5 hours 12 minutes
