Question

Jordan's activity tracker showed that when she walked for 12 minutes she took 804 steps. Karen's activity tracker showed that she walked 2,100 steps in 32 minutes. Who was walking at a faster rate?

Answer 1

Given:

Jordan's walked for 12 minutes she took 804 steps.

Karen's walked 2,100 steps in 32 minutes.

To find:

Who was walking at a faster rate?

Solution:

We need to find the unit rate of Jordan and Karen.

`\text{Unit rate}=\frac{\text{Total steps}}{\text{Total time}}`

Unit rate of Jordan,

`\text{Unit rate}=(804)/(12)`

`\text{Unit rate}=67`

Unit rate of Karen,

`\text{Unit rate}=(2100)/(32)`

`\text{Unit rate}=65.625`

Clearly, 67 > 65.625.

Since, unit rate of Jordan is greater, therefore she walked faster.
