Answer:
7/10
Step-by-step explanation:
hope this helps
We calculate both velocities:
upstream 8 miles in 2 hours = 4 miles / hour
downstream 8 miles in 1 hour = 8 miles / hour
ps -stream speed = 4 mph
ps + stream speed = 8 mph
Adding both equations
2 ps = 12 mph
paddling speed = 6 mph
stream speed = 2 mph
1. -3x + -6
2. -3x + 9
3. 2x - 6
4. -2x + 6
here u go
The answer is 1 7/30 hope this helps
