Final answer:
To determine how long it takes Antoine to cover a distance of 800 m without sandbags, we need to know his speed.
Step-by-step explanation:
To calculate the time it takes for Antoine to cover a distance of 800 m without sandbags, we need to know his speed. If we have his speed in meters per second (m/s), we can use the formula: time = distance/speed. Let's assume his speed is v m/s.
distance = 800 m
time = distance/speed = 800/v. Therefore, it will take Antoine approximately 800/v seconds to cover a distance of 800 m without sandbags.
