A bicycle is traveling at 22 miles per hour. How many feet will it cover in 30 seconds? Round your answer to the nearest tenth of a foot.

 The answer is:  " 322.7  ft. "

_______________________________

Step-by-step explanation:

First:

Convert:  " 22 mi /h" ; to:  " ft / s " ;

______________________

Note the following exact conversions:

______________________

1 mi = 5280 ft. ;

1 h = 60 min.

1 min = 60 s ;

______________________

=  ? ft/sec. ?

______________________

From the "left-hand side" of the equation:

_____________________

1) The units of "mi" ["mile(s}"] cancel out; since:  "mi/mi" = 1 .

_____________________

2) The units of "h" ["hour(s)"] cancel out; since:  "h/h" = 1 .

_____________________

3) The units of "min" ["minute(s)"] cancel out; since:  "min/min" = 1.

_____________________

And we are with units of "ft/s" ["feet per second"] :

_____________________

→  " ";  Using calculator:

_____________________

           = " " ;  Using calculator:

______________________

           = " " ;

_____________________

Now, we are asked:

_____________________

"How many feet will it cover in 30 seconds?"

_____________________

  To solve:

______________________

  " " ;

______________________

Note: The units of "s" ["second(s)"] on the "left-hand side" of the equation; cancel out to "1" ; since:  "s/s" = 1 ;  

______________________

And we have:

______________________

 " ( ) ft ;

________________________

       →   ft ;

 {Note:  To multiply by "10"; move the decimal one space to the right; or use calculator to get the value;

________________________

Second:

→  We are asked to round our answer to the "nearest tenth of a foot" ;

_________________________

 We have:  " 322.666666.... ft." :

__________________________

Note:  "322.666..."

 The "tenths" place has a digit of "6".

__________________________

The question is:  To round to the nearest tenth:

Do we round to "322.6" ? or round up to: "322.7" ?

To determine this, we examine the next following decimal; that is,

the "hundredths" place.  

 If the digit within the hundredths place is:  "0, 1, 2, 3, or 4" ; then, we "round down" to "322.6 ".

 If the digit within the hundredths place is:  "5, 6, 7, 8, or 9" ; then, we "round up" to "322.7 ".

___________________________

In our case, the digit within the hundredths place is "6" ;

 As such, we round to: "322.7" .

___________________________

The answer is:  " 322.7  ft. "

In geometry, an isosceles triangle is a triangle that has two sides of equal length. Sometimes it is specified as having exactly two sides of equal length, and sometimes as having at least two sides of equal length, the latter version thus including the equilateral triangle as a special case.
