a train 520 m long can cross an electric pole in 20 sec and then find the speed of the train?
Choose the most appropriate option:
A) 88 kmph
B) 94 kmph
C) 72 kmph
D) 16 kmph
E) 18 kmph
<gadget id="calculator">520 / 1_000</gadget>
<output>13/25 = around 0.52</output>

divide(divide(520, const_1000), divide(20, const_3600))
"length = speed * time speed = l / t s = 520 / 20 s = 26 m / sec speed = 26 * 18 / 5 ( to convert m / sec in to kmph multiply by 18 / 5 ) speed = 94 kmph answer : b"
