A bird flies with a speed of 10 km/h and a car moves with uniform speed of 8 km/h. Both starts from B towards A (BA = 40 km), at the same instant. The bird having reached A, flies back immediately to meet the approaching car. As soon as it reaches the car it flies back to A. Thus the bird repeats till both the car and the bird reach A simultaneously. The total distance flown hy the bird is [see Fig. 3.7]

A

80 km

B

40 km

C

50 km

D

can not be determined

Text Solution

Verified by Experts

The correct Answer is:
d
Time taken by car = `40//8 =5` hour. Distance flown by bird ` = 5 xx 10 = 50` km

A bird is flying towards south with a velocity 40km/hr and a train is moving with a velocity 40km/hr towards east. What is the velocity of the bird w.r.t. an obserber in train:-

Two trains are approaching each other on the same track with velocity 100 km/h and 50 km/h. When they are at a distance of 300 km from each other, a bird starts flying from train 1 towards train 2. When the bird reaches train 2, it instantly reverses its direction and flies again towards train 1. This process continues till the bird is trapped between the trains when they collide. If the bird always travels at a constant speed 200 km/h, the total distance the bird flies is:
