Answer:

Rate in still water = 27 mph

Rate in the current =36 mph

Step-by-step explanation:

The rate is the speed the boat use to travel in the water

The distance travelled upstream = 108 miles

The time taken to travel upstream = 4 hours

The rate in still water /upstream = 108/4 = 27 mph

The rate in the current /downstream = 108/3 =36 mph
