<output>5/4 = around 1.25</output>
1.25 miles/minute   d) 20istance covered in 40 minutes= 1.25 * 40 = 12.5 * 4= 
<gadget id="calculator">12.5 * 4</gadget>
<output>50</output>
50 miles   d) 20istance covered in the current direction= d) 20istance covered from the opposite direction (since car returns back to starting point)   Let x be the miles driven before turning   10 + x = 50 - x   2x = 40   x = 20   Answer: d) 20
