<PRE><B>Question 92087</B>
A car travels on the freeway at an average speed of 54  miles per hour,How many miles does it travel in 3 hours 40 minutes
First convert the time to hours.
3hr + 40 min*(1hr/60min)
3hr+{{{40/60)}}}hr
3hr+{{{2/3}}}hr
{{{3(3/3)hr+(2/3)hr}}}
{{{(9/3)hr+(2/3)hr}}}
{{{(11/3)hr}}}
The distance formula is: 
{{{highlight(d=rt)}}}, where d=distance, r=rate, and t=time.
r=54mi/hr and t=11/3hr
{{{d=(54mi/hr)*(11hr/3)}}}
{{{d=(18*11)mi}}}
{{{highlight(d=198mi)}}}
Happy Calculating!!!!</PRE>
