A wire, 224 inches long, is cut into three pieces. The first is twice as long as the second. The third is one-half as long as the second. How long is the second piece?

64in

Step-by-step explanation:

first =2* second

second=2*third since the third is half of second

first =2*2*third=4*third

now lets put them all together

first+second+third=224

4*third+2*third+third=224

7*third=224 so the third part is 32

but we need the second piece

2*32=64

i just took the test, the correct answer is .. 31.5 in.
