K is 50% faster than L. If L starts at 9 A.M. and K starts at 10 A.M. L travels at a speed of 50 km/hr. If L and K are 300 kms apart, The time when they meet when they travel in opposite direction is ?  Options:
A) 12 pm B) 22 pm C) 72 pm D) 92 pm E) 23 pm
Explanation:   let 't' be the time after which they met since L starts.   Given K is 50% faster than L   50 t + 1.5*50(t-1) = 300   50 t +75 t = 300 + 75=

<output>375</output>
375 / 125= 
<gadget id="calculator">375 / 125</gadget>
<output>3</output>
3 hrs past the time that L starts   So they meet at (9 + 3)=
