Question

Maya wants to knit a scarf that is 1.2 meters long. It takes her 20 minutes to knit 15 centimeters of length. How much time will it take Maya to knit the scarf?

A) 60 minutes
B) 80 minutes
C) 100 minutes
D) 120 minutes

Answer 1

Maya's knitting speed is
`\( \frac{15 \text{ centimeters}}{20 \text{ minutes}} \)`. To find the time required to knit 1.2 meters, we convert 1.2 meters to centimeters (1 meter = 100 centimeters). The accurate time it will take for Maya to knit the scarf is 160 minutes. The correct answer is not provided among the options.

Step-by-step explanation:

Maya's knitting speed is
`\( \frac{15 \text{ centimeters}}{20 \text{ minutes}} \)`. To find the time required to knit 1.2 meters, we convert 1.2 meters to centimeters (1 meter = 100 centimeters). Therefore, 1.2 meters is equivalent to 1.2 × 100 = 120 centimeters.

Now, we set up a proportion:

`\[ \frac{15 \text{ centimeters}}{20 \text{ minutes}} = \frac{120 \text{ centimeters}}{x} \]`

Cross-multiplying gives 15x = 2400, and solving for x (time required), we get

x =
`(2400)/(15)`

x = 160 minutes.

So, the correct answer is not provided among the options. The accurate time it will take for Maya to knit the scarf is 160 minutes, not given in the provided choices.
