Correct Answer: 1 hour
Solution : Distance = 25 km The difference between the speed in still water and the speed of the current = 40 km/hr –15 km/hr = 25 km/hr The time taken to swim a certain distance is given by the formula: Time = $\frac{\text{Distance}}{\text{Speed}}$ Substituting the values, we get: Time = $\frac{25}{25} = 1$ hour Hence, the correct answer is 1 hour.
