<PRE><B>Question 773604</B>
Dick is driving on I-75 at 65 miles per hour for 24 minutes then slows down to 55 miles per hour for 30 minutes due to construction.
 How many miles did Dick travel in 54 minutes?
:
Write a distance equation, dist = time (in hrs) * speed
:
d = [{{{24/60}}}*65] + [{{{30/60}}}*55]
reduce the fractions
d = [{{{2/5}}}*65] + [{{{1/2}}}*55]
d = 26 + 27.5
d = 53.5 mi</PRE>
