Q. A car leaves station $ X $ for station Y every 10 min. The distance between $ X $ and Y is 60 km. The car travels at a speed of 60 km/h. A man drives a car from Y station towards $ X $ station at speed 60 km/h. If he starts at the moment when one of the car leaves station $ X $ how many cars would be meet on route?

Solution:

Speed of every car is 60 km/h Distance between two stations = 60 km Time taken by car to reach the other station $ =\frac{60}{60}=1\,h=60\,\min $ Number of car leaving the station $ X $ in 60 min $ =\frac{60}{10}=6 $ When 1st car reaches the station Y the car sixth just starts its journey. The car Y will encounter the number of cars coming from X in route $ =6+5=11 $ .
