Camille can swim against the current at 1.5m/s and with the current at 3.5m/s. Write and equation that expresses each fact. How fast can she swim in still water?

v - c = 1.5

v + c = 3.5

where v is Camille's speed in still water, c is the speed of the current

Solve for v

To express Camille's swimming speeds against and with the current, we can use the following equations:

1. She can swim against the current at a speed of 1.5 m/s.
- Let's represent this speed as V_against.

2. She can swim with the current at a speed of 3.5 m/s.
- Let's represent this speed as V_with.

Now, we need to calculate Camille's speed in still water, which is the speed at which she would swim if there were no current. Let's represent this speed as V_still.

In still water, Camille's speed against the current and with the current will be equal, denoted by V_against = V_still = V_with.

Hence, the equation that expresses her swimming speed in still water is:

V_still = V_against = V_with

Therefore, Camille can swim at a speed of 3.5 m/s in still water.
