Question

Barbara can walk 3,200 meters in 24 minutes. How far can she walk in 3 minutes

Answer 1

First you need to know how far she walks in 1 minute, so you need to divide 3,200 by 24, this equals 133.3 meters, now multiply that by two and you have 266.6. So Barbra can walks 266.6 meters in 2 minutes.

Answer 2

Barbara's speed can be represented by:
3200 meters / 24 minutes

To solve for her speed in meters per minute we will divide both sides by 24.
133 1/3 meters / 1 minute

Now let's multiply this by 3, since we want to know how many meters she can walk in 3 minutes, not 1 minute.
400 meters / 3 minutes

So the answer is 400.
