Question 294607: Breanne is rowing a boat at the rate of 5 miles per hour. She can row 7 miles downstream, with the current, in the same amount of time it takes her to row 3 miles upstream, against the current. The following equation can be used to find the speed of the current stream:
7 over 5+c = 3 over 5-c
what is the speed of the current in the stream? Answer by helpnalgebra(91) (Show Source):
You can put this solution on YOUR website! (7)/(5)+c=(3)/(5)-c
c+(7)/(5)+c=(3)/(5)
2c+(7)/(5)=(3)/(5)
2c=-(7)/(5)+(3)/(5)
2c=-(4)/(5)
(2c)/(2)=-(4)/(5)*(1)/(2)
c=-(4)/(5)*(1)/(2)
c=-(2)/(5) answer
