Nichol walks at a constant pace of 1.2 m/s and takes 15 minutes to get to school. Sakura walks at 1.4 m/s and takes 20 minutes to get to school.
What is the difference between the distances they walked?

The difference between the distances they walked is 600 meters.

Step-by-step explanation:

Let's calculate the distance traveled by Nichol and Sakura with the following equation:

Where:

v: is the speed

t: is the time

The distance traveled by Nichol is:

And the distance traveled by Sakura is:

Hence, the difference between the distances they walked is:

Sakura traveled 600 meters more than Nichol.

Therefore, the difference between the distances they walked is 600 meters.
