Rather Than looking into bird Flying back to car & Destination Repteadely
We should just see that Both Car & Bird Travelled for Same Time
Distance Travelled by Car = 40 km
Speed of Car = 8 km/hr
Time Car travelled = 40/8 = 5 hr
=> Bird fly for 5 hrs
Bird Speed = 10 km /hr
Distance Travelled by Bird = 10 * 5 = 50 km
The total distance flown by the bird is 50 km
Answer:
Explanation:
Total time taken by car,
T= s /v
=40/8 hrs
=5 hrs
Total distance flown by the bird,
s =v T
=10×5 km
=50 km
