Question 1096980: Toni rows a boat 4.5 km/h upstream and then turns around and rows 5.5 km/h back
downstream to her starting point. If her total rowing time is 48 min, for how long does she
row upstream? Express your answer to the nearest minute.
A about 44 min
B about 26 min
C about 24 min
D about 30 min Answer by greenestamps(13195) (Show Source):
You can put this solution on YOUR website! The upstream and downstream distances are the same. That means more time is spent at the lower upstream rate than at the higher downstream rate.
If you want an exact answer for the amount of time spent rowing upstream, then you can use the ratio of the speeds and the given total time to get that answer.
But since the question is multiple choice, it is easy to pick the right answer. Half of the total 48 minutes would be 24 minutes; the time spent rowing upstream has to be a bit more than that.
