<output>1/8 = around 0.125</output>

<gadget id="calculator">(1/8) * 160</gadget>
<output>20</output>

<gadget id="calculator">20 - 7</gadget>
<output>13</output>

<result>C</result>
in a 160 meters race a beats b by 56 m or 7 seconds. a ' s time over the course is:
subtract(multiply(divide(7, 56), 160), 7)
b runs 56 m in 7 sec . = > b runs 160 m in 7 / 56 * 160 = 20 seconds since a beats b by 7 seconds , a runs 160 m in ( 20 - 7 ) = 13 seconds hence , a ' s time over the course = 13 seconds answer : c
