Answer:
Rate in still water = 27.5 mph
Current's rate = 12.5 mph
Step-by-step explanation:
Let
x mph = row team rate in still water
y mph = current's rate
<u>Upstream:</u>
Distance = 30 miles
Time = 2 hours
Rate = x - y mph
Then

Distance = 30 miles
Time = 45 minutes
hour
Rate = x + y mph
Then

From the first equation:

From the second equation:

Add these two equations:

Subtract these two equations:
