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
