On a float trip, Kim traveled 48 miles downstream in the same amount of time that it would take her to row 30miles upstream. If her speed in still water is 13 mph, find the speed of the current.
Answers: 2
, where:
is the time 
is the distance
is the speed of the current
. We also know that Kim traveled 48 miles downstream, so 
. Replacing values we get 
equation (1)
. We also know that Kim traveled 30 miles upstream, so 
. Replacing values we get 
equation (2)
