Show how you calculated each answer.

Answer 1

If she travels 1 block every minute, it will take her 24 minutes to get to her friends house. If she travels 2 blocks every minute it will take her 12 minutes to get there.

Explanation:

24 blocks ÷ 1 minutes = 24 minutes

24 blocks ÷ 2 minutes = 12 minutes

Answer 2

1) 24 minutes

2) 12 minutes

Explanation:

1) ∵ Meredith travels 1 block every minutes,

So, her speed = 1 block per min,

Total blocks = 24,

`\text{The time taken by her }=\frac{\text{Total blocks}}{\text{Her speed}}`

`=(24)/(1)`

= 24 minutes,

2) Now, if she travels 2 blocks every min,

Then her speed is 2 blocks per min,

Thus, the time taken by her =
`(24)/(2)`

= 12 minutes
