Her age will be twice as old as her age now. How old is she now?

A canoe makes a round trip from campsite A to B, which are 10 km apart. The speed of the canoe in still water is \(u\) km/h, and the speed of the water current is \(v\) km/h. The upstream trip takes 40 minutes, and the downstream trip takes 25 minutes. What are the values of \(u\) and \(v\)?

Answer :

Final answer:

The problem refers to solving a system of linear equations, where the two equations express the canoe's downstream and upstream speeds. Solving this system gives the speed of the canoe in still water and the speed of the water current.

Explanation:

The subject of your problem seems to be about solving a system of linear equations. Specifically, the problem can be interpreted as two equations involving canoe speeds as follows:

  1. u + v = 10 km/(25/60 h) because downstream the speeds add up.
  2. u - v = 10 km/(40/60 h) since upstream the current is against the canoe, hence the speeds subtract.

Solving this system will give the values of u (the speed of the canoe in still water) and v (the speed of the water current).
