Answer 1

Answers:

B. 2mi= 10,560ft

C. 1/2 mi= 2,640 ft

D. 0.5mi= 880 yd

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:

$24\text{ ft }\times\frac{12\text{ in}}{1\text{ ft}}=288\text{ in}$

Then, option A is an incorrect conversion.

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

$2\text{ mi }\times\frac{5280\text{ ft}}{1\text{ mi}}=10560\text{ ft}$

Therefore, option B is a correct conversion

For C, 1/2 miles are equal to:

$\frac{1}{2}mi\times\frac{5280\text{ ft}}{1\text{ mi}}=2640\text{ ft}$

Option C is a correct conversion

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

$0.5\text{ mi }\times\frac{5280\text{ ft}}{1\text{ mi}}\times\frac{1\text{ yd}}{3\text{ ft}}=880\text{ yd}$

Option D is a correct conversion

For E, 0.5 ft is equal to:

$0.5\text{ ft }\times\frac{12\text{ in}}{1\text{ ft}}=6in$

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
