Question 965603
.
{{{time=distance/rate}}}
So when time is the same: 
(c=rate of current)
{{{325mi/(59mph+c)=265mi/(59mph-c)}}} Cross multiply
{{{(325mi)(59mph-c)=(265mi)(59mph+c)}}}
{{{19175mi^2/hr)-(325cmi)=(15635mi^2/hr)+(265cmi)}}} Subtract 15635mi^2/hr from each side
{{{(3540mi^2/hr)-(325cmi)=265cmi}}} Add 325cmi to each side.
{{{3540mi^2/hr=590cmi}}} Divide each side by 590mi
{{{6mi/hr=c}}} ANSWER: The rate of the current is 6 mph.
