To convert inches per second to feet per minute, which of the following conversation factors would be used? (it's two answers)

1 min/60 sec

60 min/1 hr

12 in/1 ft

1 ft/12 in

Answer would be:

1ft/12in and 60sec/1min

Step-by-step explanation:

First think of the units that you are converting separately:

inches → feet

seconds → minute

So you need to find the units that match those.

Now let's look at the units as a whole:

Now the trick in converting is whatever you are trying to cancel out, you put the factor on top. Since you want to cancel out seconds, you will need to make sure that the conversion factor you will has seconds on top.

For the inches to feet, since inches is what you need to cancel out, then use the conversion factor that has inches in the bottom.

step-by-step explanation:

here x represents the height of the pole,

and, the height of the shadow of the pole is 12 feet.

also, the angle of elevation from the top of the pole is 40°,

therefore,

by the low of sine,

which is the required equation for finding the value of x,
