Question:
A bird is fiying to and fro between two cars moving towards each other on a straight road. One car has speed of 28km/hr,will the other has the speed of 27km/hr. the bird starts moving from the first cae towards the other car and is moving with the spreed of 36km/hr and when the two cars were seperated by 36km.Find the total distance covred by the bird?
Answer:
Velocity of car A = 28 Km/hr
Velocity of car B = 27 Km/hr
Relative velocity of A with respect to car B = 28 + 27 = 55 Km/hr
Distance between cars = 36 Km
Time at which both cars will meet = Distance / Velocity = 36 / 55 = 0.65 hr
Speed of the bird = 36Km /hr
Distance covered by the bird = Speed of the bird * Time taken till both cars meet = 36 * 0.65 = 23.4 Km
