    Answer:

    Let two cars A and B are separated by 80 km apart. If the cars A and B moves in the same time, both the cars will meet together in 8 hours. If the cars A and B moves in opposite direction, both the cars will meet together in 1 hour and 20 minutes.

    Step-by-step explanation:

    Speed of car A = 35 kmph & that of B = 25 kmph

    To find:

    Find the speed of the car = ?

    Solution:

    Let two cars A and B are separated by 80 km apart.

    Let speed of A be x km/hr and speed of B be y km/hr

    Distance to be travelled = 80 km

    If the cars A and B moves in the same time, both the cars will meet together in 8 hours.

    This can be written as

    If the cars A and B moves in opposite direction, both the cars will meet together in 1 hour and 20 minutes.  

    This can be written as

    Solving equation (1) & (2), we get

    Putting a = 35 kmph in equation (1), we get,

    Speed of car A = 35 kmph & that of B = 25 kmph
