Two bodies start from opposite ends P & Q at the same time and move towards each other with speeds S(1) & S(2). After meeting each other, they take times of T(1) & T(2) to reach their destinations.
Two bodies start from opposite ends P &; Q to reach their destinations at the same time and move towards each other with speeds S(1) & S(2). Before meeting, they take times of T(1) & T(2) to reach the meeting point.
are the formula involved in both the conditions same..?(i.e relationship between the times taken and the speeds )
