Step-by-step explanation:
It is given that, swimmers swim a total of 8 laps of a 50-meter-long swimming pool. We need to find the distance traveled by a swimmer in this meet.
Distance = total path covered during entire journey
In every lap he covers a distance of 50 m. It means in 8 laps it will cover 8×50 = 400 meters.
Displacement = shortest path covered
After 8 laps, the swimmer ultimately comes to the starting point. It means its displacement is equal to 0.
