Tom [10]
Start by converting 300 feet to miles and 2.92 seconds to hours.

300 feet      1 mile
----------- x -------------- = ?

2.92 sec              1 hr
----------------- * ---------------- =  ?
        1               3600 sec

Reduce each of the above fractions.  Then convert  300 feet
                                                                                  -------------- to the 
                                                                                    2.92 sec

kompoz [17]
A book is sold in Belize for 80.39 Belize dollars.
In Brazil, it sells for 63.65 Brazilian reals.

The exchange rate of US Dollars to Belize Dollars is 1:1.9246
<span>The exchange rate of US Dollars to Brazilian Real is 1:1.7880
</span>
If we convert the two into dollars,
Belize Dollars 
1 : 1.9246 = X : <span>80.39 
1.9246X = 80.39
X = $ 41.77 

</span>Brazilian Real
1 : 1.7880 = X : 63.65 <span> 
</span>1.7880X = 63.65 <span>
X = $ 35.60
</span>
Difference = $ 41.77 - $ 35.60
Difference = $ 6.17

<span>So, in Belize the book is more expensive by $ 6.17</span>
