Question 235031
<font face="Garamond" size="+2">


45 minutes is *[tex \Large \frac{45}{60}\ =\ \frac{3}{4}\ =\ 0.75] hour.


If you go 64 miles per hour for 1 hour, you go 64 times 1 equals 64 miles.  If you go 64 miles per hour for 2 hours, you go 64 times 2 equals 128 miles.  Therefore, if you go 64 miles per hour for 4 and three-quarters hours...


Depending on whether you would rather work with fractions or decimals, either:


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 64\ \times\ 4\frac{3}{4}] which is the same as *[tex \LARGE 64\ \times\ \frac{19}{4}] 


or 


*[tex \LARGE \ \ \ \ \ \ \ \ \ \ 64\ \times 4.75]


You can do your own arithmetic.
