Answer:
<em>Distance= 187.5 m
</em>
<em>Displacement= 12.5 m</em>
Explanation:
<u>Distance And Displacement
</u>
The question doesn't say what the length of the pool is, so we are assuming two things:
The pool is 50 m long.
One lap is one pool length, i.e. 50 m
Grant swims 3 3/4 laps. If we add up the total distance is 50*(3.75)=187.5 m
Grant starts in one end, swims one pool, then swims back one pool. Right now, he has zero displacement
Then he swims another pool and returns only 3/4 of the lap, which means he still needed 1/4*50 m=12.5 to arrive at his starting point. The final displacement is the subtraction of the final position minus the initial position, i.e. 12.5 m - 0 m= 12.5 m
Answer:
Distance= 187.5 m
Displacement= 12.5 m
