two cars are moving in the same direction one with velocity 36 km/hr in front and the other 54 km/hr behind it by 100 m in what time the car behind it will overtake the front car

Solution

Dear Student

Let t hrs be the time to overtake

Distance travelled by A = 54 t km = 0.1 + Distance travelled by B = 0.1km +36t

= 54 t = 0.1+ 36 t

= 18 t = 0.1 km
t = 0.1 /18 =0.0055 hr = 20 sec

Q. Two cars start towards each other at the same time. The distance between the cars is 3000 km. One travels at 60 km/hr and another at 90 km/hr. A bird starts with one of the cars and flies at 400 km/hr towards the other one. When it gets to the other car, it turns and flies back towards the first and continues this to and fro flying when the cars are moving towards each other. Distance travelled by the bird before the cars pass each other is:
