Can someone help me with this question on conversions? A baseball pitcher pitches a ball at #92# miles per hour. Which of the following would give it in feet per second?

Answer 1

First and third

Since a mile is 5,280 feet long, you could multiply 5,280 by 92 to find the feet per hour. Next, you would use the third conversion to convert the hour into minutes and then seconds.

As written, there is no way to get from the one measure to the other. See below for more:

Simply examining the units on this query will allow us to determine which conversion units are useful.

#"miles"/"hour"->"feet"/"second"#

The first conversion factor will work well for converting miles to feet.

I'll write this summary out both ways, but to go from hours to seconds... with the options listed, we can't get there (I assume that last conversion was meant to be 60 seconds to 1 minute, or maybe 3600 seconds to 1 hour, but as stated it's an incorrect conversion factor).

#cancel"miles"/cancel"hour"("feet"/cancel"mile")(cancel"hour"/cancel"minutes")(cancel"minutes"/"seconds")->"feet"/"second"#

or

#cancel"miles"/cancel"hour"("feet"/cancel"mile")(cancel"hour"/"seconds")->"feet"/"second"#

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
