Question 1015810: ina crespo rowed 12 miles down the habashabee river in 1.5 hours , but the return trip took her 4 hours . find the rate ina rows in still water and the rate of the current . let x represent the rate ina can row in still water and let y represent the rate of the current. Answer by josgarithmetic(39623) (Show Source): You can put this solution on YOUR website! Unknown Variables x rate in still water, y rate of river current;
Meaning of known variables:
p time done down river
n time done up river
d distance each way
rate time distance
DownRiver x+y p d
UpRiver x-y n d
RT=D basic travel rate relationship rule relating rate time distance
Solve this system for x and y.
IF you solve this system all in symbols, then you have a solution which will
fit ALL examples which fit the form of the exercise.
