Assuming, 30 mph is a constant or average speed, you can use the equation:Speed = Distance / Time
Solve for Time:
Speed = Distance / Time
Time = Distance / Speed
Plug in your numbers:
t = 428 miles / ( 30 miles / hour )
miles cancel out, and leave hours
t = 428/30 hours leaving you with about 14.2667 hours
If you want time to be in hours and minutes:
14.2667 - 14 = 0.2667 hours (remove the 14 hours, we'll add it at the end)
0.2667 hours x ( 60 minutes / 1 hour ) = .2667 x 60 minutes = about 16 minutes
The answer is about 14 hours and 16 minutes
