At 3:00 pm, a car has driven 40 miles east. It will continue to drive east at 0.8 minutes per mile and then turn around and drive at 0.8 minutes per mile back to its original starting point. How far can it drive before turning around in order to arrive back to its original starting point by 3:40 pm? Choose the correct choice from the following:
A) a) 10  B) b) 5  C) c) 12  D) d) 13  E) e) 14
0.8 minutes --&gt; 1 mile   1 minute --&gt; 1/0.8 = 10/8= 
<gadget id="calculator">10/8</gadget>
<output>5/4 = around 1.25</output>
1.25 miles/minute   Distance covered in 40 minutes= 1.25 * 40 = 12.5 * 4= 
<gadget id="calculator">12.5 * 4</gadget>
<output>50</output>
50 miles   Distance covered in the current direction= Distance covered from the opposite direction (since car returns back to starting point)   Let x be the miles driven before turning   40 + x = 50 - x   2x = 10   x = 5   Answer: b) 5
