Answer 1

Answers:

B. 2mi= 10,560ft

C. 1/2 mi= 2,640 ft

D. 0.5mi= 880 yd

Step-by-step explanation:

To know if the conversions are true, we need to convert for each answer option.

So, for A, we get that 24 ft are equivalent to:

`24\text{ ft }*\frac{12\text{ in}}{1\text{ ft}}=288\text{ in}`

Then, option A is an incorrect conversion.

For B, we get that 2 miles are equivalent to:

`2\text{ mi }*\frac{5280\text{ ft}}{1\text{ mi}}=10560\text{ ft}`

Therefore, option B is a correct conversion

For C, 1/2 miles are equal to:

`(1)/(2)mi*\frac{5280\text{ ft}}{1\text{ mi}}=2640\text{ ft}`

Option C is a correct conversion

For D, The number of yards equivalent to 05 miles is:

`0.5\text{ mi }*\frac{5280\text{ ft}}{1\text{ mi}}*\frac{1\text{ yd}}{3\text{ ft}}=880\text{ yd}`

Option D is a correct conversion

For E, 0.5 ft is equal to:

`0.5\text{ ft }*\frac{12\text{ in}}{1\text{ ft}}=6in`

Then, option E is an incorrect conversion.

So, the answers are:

B. 2mi= 10,560ft

C. 1/2 mi= 2,640 ft

D. 0.5mi= 880 yd
