Choose the correct choice from the following answers:
A) 100 m	B) 150 m	C) 187 m	D) 167 m	E) 197 m

<output>40_000</output>

<gadget id="calculator">40_000 / 3_600</gadget>
<output>100/9 = around 11.111111</output>

<gadget id="calculator">(100/9) * 9</gadget>

<result>A</result>
a train running at the speed of 40 km / hr crosses a pole in 9 sec. what is the length of the train?
multiply(divide(multiply(40, const_1000), const_3600), 9)
"speed = 40 * 5 / 18 = 100 / 9 m / sec length of the train = speed * time = 100 / 9 * 9 = 100 m answer : a"
