## CURRENTly...

Made this up as my xmas gift to ya'll ! Easy nuff...

Boat leaves point A, at constant speed b mph,

against a current of speed c mph for 1st hour.

The current's speed increases by 1 mph hourly.

Like, boat nets (1st 3 hours): b-c, b-(c+1), b-(c+2)....

At point B, after u hours, a hat falls out of

the boat, and floats with the current towards A,

and gets to A after travelling for v hours.

Boat continues for another w hours to point C,

where it turns around and heads towards A.

YES, the boat reaches A at same time as the hat!

Distance AB = d miles, distance BC = e miles.

Be advised that e - d = 39 miles.

Please note that w = 6 hours; you're welcome.

b, c, d, e, u, v, w are all integers.

Find b and v.
