A man takes his motor boat down the river to his pub. Going with the current, he can cover the 2 miles in 4 minutes. Returning against the current, which is steady, it takes him 8 minutes.

How long would it take him at still water, when there is no current?

23.42/42.94 and 5.2/4.256 How?

In most classes like Physics/Calculus you'll just use a calculator if you need to compute these, so I forgot how to do them by hand. 23.42 is smaller than 42.94, and they're both decimals, this makes it tricky for me.

My last question is how would I approximate something like cos(2) or ln(3) without using a calculator?

I intend to make a hillbilly swimming pool by using a great sheet of plastic in the back of my old pickup truck and filling it with water. I just don't want to put too much weight in it and damage the leaf springs or other things. I own a '79 chevy 1/4 ton stepside in fair condition. P.S. I mean no offense to actual hillbillies :)
