1Data insufficient....
It has to be provided whether the 2 cars are moving towards each other or they are travelling in the same strt. line such that one catches up with the other
1I m considering the cars to b travelling in same line...
Then, S(car 1)=11+5t {It needs to cover additional 11m to meet it, along with the distance car 2 travels}
S(car 2)=1/2.(1).t^2
equating both, I m getting ans a 47/2 seconds
I dont know where I m getting wrong, I even tried some other permutations to mould tthe Q a bit like if car 1 was ahead, but no answer matches, and option (d) is not correct since it is sure that car 2 will ovrtake car 1
1If you can't find any question with complete data either leave it or go for "None of These".
