Over a period of 12 weeks, Carlos ran an average of 21 miles per week. How many kilometers is this? Round your answer to the nea
velikii [3]

Answer:

405.80

Step-by-step explanation:

So, we know Carlos ran 21 miles per week, for 12 weeks....

That makes 21 mi/wk x 12 weeks = 252 miles.

Then we know each km is 0.621 mile.

So, we divide 252 miles by 0.621 mile/km to get= 405.80 km

Dividing miles by miles/km gives us the unit we want (km).

<u>There was a trap in this question,</u> because if instead of dividing the 252 miles by 0.621 you would have multiplied it, you would have gotten another answer listed... just not the right one. :-)

Can sum 1 help wit dis qustion plz?
trapecia [35]
Hello!

You first have to find the scale factor between the triangles

To do this you divide the new side length by the old one

9 / 6 = 1.5

They multiplied the smaller triangle by 1.5 to get the bigger one

Do this to find the missing length

8 * 1.5 = 12

The answer is 12

Hope this helps!
