Question

Ciera can swim 400 meters in 1 minute and 20 seconds. What is Ciera’s average rate in meters per second?

Answer 1

5 MPS

Explanation:

If Ciera can swin 400 meters in 1 minute and 20 seconds,

400 meters = 1 minute 20 seconds (1 1/3 minutes).

Divide both sides by 1 1/3.

400/ 1 1/3 = 300

Since it asks in seconds, divide by 60.

300/60=5

Answer 2

5 meters per second.

Explanation:

There are 60 seconds in 1 minute:

1 minute 20 seconds = 60 seconds + 20 seconds = 80 seconds.

Divide the amount of meters swam (400) with the total amount of seconds used (80) to get the average meters per second:

(400 meters)/(80 seconds) = 5 meters/second.

5 is your answer.
