Question 284687: There once was a salmon who tried to swim upstream to the place where she was born. She had to swim 1,010 feet upstream to reach the shady pool of water where she had once hatched from her egg. Every five minutes she swam 30 feet upstream, but then in the next two minutes, while she rested, the rushing current would push her 10 feet back downstream. She continued this way, swimming for five minutes then resting for two minutes, until she reached her destination.
How long did it take her to swim the entire 1,010 feet?

I think this is the ans:
In 5 min , 30 feet is covered ,next 2 min 10 feet backwards.
So in 7 min only 20 feet . OK.
20 feet -----> 7 min
1 feet ------> 7/20 min
1010 feet ---> ( 7*1010 ) / 20 min
= 353.5 min (nearly 6 hrs,Shooo. )

Happy.......
