f(x) = 6 * 9 = 54 f(x)=54
f(x) = 6*37=222 f(x)=222
f(x)=6*109=654 f(x)=654
f(x)=6*6=36 f(x)=36
-- If one train covers 40 km per hour and the other one covers 60 km per hour,
then they reduce the gap between them at the rate of 100 km per hour.
-- Since they begin 30 km apart, they meet and crush the crow in 30/100 = 0.3 hour.
-- The crow's speed is 80 km per hour. In 0.3 hour, he covers 0.3 x 80 = <em><u>24 km.</u></em>
<u>Note:</u> 40 km/hr and 60 km/hr are speeds, not velocities.
