<PRE><B>Question 628664</B>

Donna is late for a sales meeting after traveling from one town to another at a speed of 32 mph. If she had traveled 4 mph faster, she could have made the trip in 1/2 hr less time. How far apart are the towns?


Let distance between the towns be D


Then: {{{D/32 - D/(32 + 4) = 1/2}}}


{{{D/32 - D/36 = 1/2}}}


9D – 8D = 144 ----- Multiplying by LCD, 288


D, or distance between the towns = {{{highlight_green(144)}}} miles
