Question

Neva swam 3 complete laps in a 50 meter pool (1 lap is to the other side and back) express your answer in meters.

What is the distance and displacement

Answer 1

Distance covered by Neva = 300 m

Displacement of Neva = 0 m

Step-by-step explanation:

Given:

Length of the pool = 50 meter

Number of laps Neva swam = 3

1 lap is to swim to the other side and back.

To find the distance and displacement.

Solution:

To calculate the distance swum by Neva we will find the total length covered by Neva in 3 laps.

1 lap is 50 meters to the other side and 50 meters back

So, the length of 1 lap =
`50\ m+50\ m=100\ m`

Total length of 3 laps =
`3* 100\ m = 300\ m`

To calculate the displacement we will find the distance between initial position and final position.

We, see that on completing 3 laps Neva returns to her starting point. Thus the initial and final position are the same. Do, the distance between initial position and final position will be = 0 m

Distance covered by Neva = 300 m

Displacement of Neva = 0 m
