Question

To convert inches per second to feet per minute, which of the following conversion factors would be used? Select all that apply. 1 min/ 60 sec 60 min/1hr 60 sec/1min 12in/1ft 1hr/60min 1ft/12 in

Answer 1

Answer:

$\frac{inch}{sec}=5 feet/sec$

Step-by-step explanation:

We have to change

inches / second into feet /min

and we know that

$1 inch=\frac{1}{12}feet$

$1 sec=\frac{1}{60}min$

now, we can replace these values

$\frac{inch}{sec}=\frac{\frac{1}{12} }{\frac{1}{60} } feet/sec$

now, we can simplify it

$\frac{inch}{sec}=\frac{1\times 60 }{12\times 1} feet/sec$

$\frac{inch}{sec}=5 feet/sec$

Answer 2

Answer:

Option 1 and 4 are correct.

Step-by-step explanation:

To find : To convert inches per second to feet per minute, which of the following conversion factors would be used?

Solution :

To convert inches per second to feet per minute, we use the conversion

1 feet = 12 inches

1 inches = $\frac{1}{12}$ feet.

1 minute = 60 seconds

1 second = $\frac{1}{60}$ minute.

i.e. option 1 and 4 are correct.

Applying conversions,

$\frac{\text{inches}}{\text{second}}=\frac{\frac{1}{12}\text{ feet}}{\frac{1}{60}\text{ minute}}$

$\frac{\text{inches}}{\text{second}}=\frac{60}{12}\frac{\text{ feet}}{\text{ minute}}$

$\frac{\text{inches}}{\text{second}}=5\frac{\text{ feet}}{\text{ minute}}$
