Explanation

Distance = 2000 meters. Speed = 12 m/s. Time = Distance / Speed = 2000 / 12 = 166.66 seconds. 166.66 seconds = 2 minutes and 46.66 seconds, which is approximately 2 minutes 47 seconds.

AI explanation

Using the conversion 1 km = 1000 m, the total distance to school is 2 x 1000 = 2000 m. Applying the formula Time = Distance / Speed, the time taken cycling at 12 m/s is 2000 / 12 = 166.67 seconds. Converting this to minutes and seconds gives 2 minutes and 46.67 seconds, which rounds to 2 minutes 47 seconds. The result is 2 minute 47 seconds.
