Question

John’s go kart went 10 laps around a 1320-foot track in 12 minutes. How fast was he traveling in kilometers per hour?

Answer 1

20.1169 Km/hr

Step-by-step 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
