Final answer:

Han runs at a speed of 5 meters per second and will take 600 seconds or 10 minutes to run 3000 meters.

Explanation:

If Han can run 100 meters in 20 seconds, then Han's running speed is 5 meters per second (100 meters divided by 20 seconds). To calculate how long it will take him to run 3000 meters, we can use the formula Time = Distance ÷ Speed. So, Time = 3000 meters ÷ 5 meters per second, which equals 600 seconds or 10 minutes. Therefore, it will take Han 600 seconds or 10 minutes to run 3000 meters assuming a constant speed throughout the run.

Answer:

600 seconds

Step-by-step explanation:

In this case we have to calculate the speed;

Speed = Distance/Time

Speed = 100/20 = 5 mph

Next to get our answer we have to calculate the amount of time

Time = Distance/Speed

Time = 3000/5 = 600 seconds
