Answer:
20.1169 Km/hr
Explanation:
10 laps around a 1320-foot track in 12 minutes.
Total distance = 10 * 1320 foot = 13200 foot
Time = 12 minutes
Converting to Kilometers and hour;
1 Foot is equal to 0.0003048 Kilometers;
13200 foot = x kilometer
Total distance = 4.02336 kilometer
Time = 12 / 60 = 0.2 hour
Speed = Distance / Time = 4.02336 / 0.2 = 20.1169 Km/hr
