Two cars start at the same time from A and B which are 120 km apart. If the two cars travel in opposite direction they meet after one hour and if they travel in same direction ( from A towards B) then A meets B after 6 hours. What is the speed of the car starting from A?	Choose the correct choice from the following answers: A) 70 kmph B) 120 kmph C) 60 kmph D) Data Inadequate E) None of these
Let, speed of car from A towards B = x km/hr   Let, speed of car from B towards A = y km/hr   Two cars start at same time which 120km apart = x + y = 120-----(i)   Travel in same direction, A meets B after 6hr = 6x-6y = 120-----(ii)   By Solving equation (i) and (ii), we get   12x = 840   x = 840/12=

<output>70</output>
70km/hr   Substituting x value in eqn (i) or (ii), we get   y= 50km/hr   So, speed of car starting from 70kmph.   70 kmphNSWER:70 kmph
