A has left the destination well 2 hrs before B and the speed of A is 15km/hr which means in these extra 2 hrs it will cover the distance of 30 kms extra where as the difference of the distance covered b/w A and B is 3kms for each hour so on this way B will simply take 10 or more hrs to bypass A.simple is that no need to hold the pen even
