A Correct answer
Explanation

Distance = Speed * Time. Time = 3 hours 40 minutes = 3 + 40/60 = 11/3 hours. Distance = 3 * (11/3) = 11 km. Cycle speed = Distance / Time = 11 / 11 = 1 km/hr.

AI explanation

Since the distance covered remains constant, it is calculated as 3 km/hr multiplied by the original time of 3 hours and 40 minutes, which converts to 11/3 hours, yielding a total distance of 11 km. To find the speed of the cycle, we use the formula speed equals distance divided by time, dividing the 11 km distance by the new time of 11 hours. This gives a speed of 1 km/hr.
