Final answer:
It takes 3 minutes to complete 1 lap on the go-kart track.
Step-by-step explanation:
To calculate how long it takes to complete 1 lap on a go-kart track, we can use the equation Speed = Distance/Time. In this case, the distance is 1 mile and the speed is 20 miles per hour.
We can rearrange the equation to solve for time: Time = Distance/Speed.
Substituting the values, we get Time = 1 mile / 20 miles per hour. By simplifying, we find that it takes 0.05 hours to complete 1 lap.
To convert this time to minutes, we can multiply by 60 minutes in an hour, so it takes;
0.05 hours * 60 minutes per hour = 3 minutes to complete 1 lap on the go-kart track.
