a train 600 m long can cross an electric pole in 20 sec and then find the speed of the train?	Select the correct option:
A) 76 kmph	B) 108 kmph	C) 72 kmph	D) 34 kmph	E) 91 kmph
<gadget id="calculator">600 / 1_000</gadget>
<output>3/5 = around 0.6</output>

<gadget id="calculator">20 / 3_600</gadget>
<output>1/180 = around 0.005556</output>

<gadget id="calculator">(3/5) / (1/180)</gadget>
<output>108</output>

<result>B</result>
a train 600 m long can cross an electric pole in 20 sec and then find the speed of the train?
divide(divide(600, const_1000), divide(20, const_3600))
"length = speed * time speed = l / t s = 600 / 20 s = 30 m / sec speed = 30 * 18 / 5 ( to convert m / sec in to kmph multiply by 18 / 5 ) speed = 108 kmph answer : b"
