The cycle is traveling at a speed of 20 km/h. The distance between stop A and stop B is not given in the question, so we cannot calculate the exact time it will take for the cycle to reach stop B. However, since the cycle is traveling at a slower speed than the bus (60 km/h), it will take longer for the cycle to reach stop B compared to the bus. Therefore, the only option that makes sense is 60, as it is the only answer that is less than 100.
