A starts at 11:00AM and travels at a speed of 4km/hr. B starts at 1:00PM and travels at 1km/hr for the first 1hr and 2km/hr for the next hr and so on. At what time they will meet each other ?	Choose the correct choice from the following choices
A) 9:38pm
B) 9:48pm
C) 9:58pm
D) 9:28pm
E) 9:18pm
though there is no mention of direction,we hav to consider that both A&amp;B starts from same side.   let at the end of 10hr(i.e at 9pm from 11am),A travelled 40kms in 10hr and B travelled 36kms(1+2+..+8)in 8 hr.   we cant take 11 hr bcoz after 11hr(i.e at 10pm)B has crossed A.   so,A &amp; B are  (40-36)=

4kms far from each other.   now speed of A=4km/hr &amp; B=9km/hr.   relative speed= 9-4= 
<gadget id="calculator">9-4</gadget>
<output>5</output>
5km/hr.   so,time taken by them to meet= (4/5)hrs=48min.   so A and 9:48pm meet At 9:48pm   ANSWER:9:48pm
<result>B</result>
