Final answer:
The duration for Mark to run 2 laps depends on the length of one lap. Once known, you can apply the formula Time = Distance / Speed to find the answer.
Step-by-step explanation:
To determine how long it would take for Mark to run 2 laps, we need to know the length of one lap. Without this crucial piece of information, we cannot calculate the total time. However, once you know the total distance Mark needs to cover, you can use the formula:
Time = Distance / Speed
For instance, if one lap is 400 meters, then 2 laps would be 800 meters. Given that Mark runs at a pace of 5 meters/second, the time to run 2 laps would be:
800 meters / (5 meters/second) = 160 seconds.
