Answer 1

To find the average speed, you can use the formula:

\[ \text{Average speed} = \frac{\text{Total distance}}{\text{Total time}} \]

In this case, the athlete swims a total distance of 25 meters in a total time of 15 seconds. Plugging in the values:

\[ \text{Average speed} = \frac{25 \text{ meters}}{15 \text{ seconds}} \approx 1.67 \text{ meters per second} \]

Rounding to one decimal place, the average speed is approximately 1.7 meters per second.

Therefore, the correct response is 1.7.
