First the units of speed and distance have to be made the same.
1 km = 0.6 miles
Thus, a velocity of 104 km/hr =104*0.6, i.e. 62.4 miles/hr
Distance remaining to be covered= 330 miles.
Your constant speed is 62.4 miles/hr
From speed-displacement-time relations,
Displacement or distance=speed*time
So, time=distance/speed=330/62.4 hr =5.29 hr = 5 hr 17 minutes (approximately).
Therefore, it will take 5 hr 17 minutes to reach your destination.

First you have to convert miles into km so you can solve how long it would take. So 330/.6=550 km long. If it takes an hour to drive 104 km, it would take approximetly 5.28 hours (550 miles/104 miles=5.28846... hours).
