ans : 200 miles

distance travelled by the ship by the time flight travells 180 miles is

180/10v = d/v (time is same )

d=18 miles

now let the distance where they meet from this point(180miles)is D

by this time ship travelled xtra 18miles

D/10v = D-18/v (time is same)

D=20 miles

so total distance is 180+20 = 200miles

	A	B	C
INITALLY	X	Y	Z
AFTER FIRST TRANSACTION	X-Y-Z	2Y	2Z
AFTER SECOND TRANSACTION	2(X-Y-Z)	2Y-(X-Y-Z)-2Z	4Z
AFTER THIRD TRANSACTION	4(X-Y-Z)	2{ 2Y-(X-Y-Z)-2Z }	4Z-2(X-Y-Z)-{2Y-(X-Y-Z)-2Z }

2 ans:Now the final values in each column is equal to 24 as given in the problem, so we have 3 unknowns and 3 equations .now u may proceed to the answer A=39cars, B=21cars and C=12 cars u will be getting
