A Correct answer
Explanation

Time to cycle = 50 / 12.5 = 4 hours. He rests after 12.5 km, 25 km, and 37.5 km. That is 3 rests. 3 * 20 minutes = 60 minutes = 1 hour. Total time = 4 + 1 = 5 hours.

AI explanation

Using the formula Time = Distance / Speed, the total travel time for 50 km at 12.5 km/hr is 50 / 12.5 = 4 hours. He takes rest after every 12.5 km, meaning he rests 3 times before finishing the 50 km, adding 60 minutes to the journey. The total time equals 4 hours plus 1 hour, resulting in 5 hours.
