The current in a river is 1.0 meters/second. Britney swims 300 meters against the current. If she normally swims with a speed of

2.0 meters/second in still water, how long does it take her to complete the trip?

100 is the wrong answer

Upstream=300 metres/(2-1)=300 s

Downstream=300/(2+1)=100 s

100

To find out how long it takes Britney to complete the trip, we need to consider both her swimming speed and the current in the river.

When swimming against the current, Britney's effective speed is the difference between her swimming speed and the current speed. In this case, her effective speed is 2.0 m/s - 1.0 m/s = 1.0 m/s.

We can then calculate the time it takes for Britney to swim 300 meters against the current using the formula:

Time = Distance / Speed

Time = 300 meters / 1.0 m/s

Time = 300 seconds

Therefore, it takes Britney 300 seconds to swim 300 meters against the current.
