Question 814882: A whale swimming against an ocean current traveled 60 mi in 2h.Swimming in the opposite direction,with the current,the whale was able to travel the same distance in 1.5 h.Find the speed of the whale in calm water and the rate of the ocean current.
Answer by TimothyLamb(4379) (Show Source): You can put this solution on YOUR website!
w - c = 60 / 2 = 30 mph
w = 30 + c
w + c = 60 / 1.5 = 40 mph
---
w + c = 40
30 + c + c = 40
30 + 2c = 40
2c = 10
---
c = 5
w = 35
