A & B are at a distance of 800 m. They start towards each other at 20 & 24 kmph. As they start, a bird sitting on the cap of A, starts flying towards B, touches B & then returns towards A & so on, till they meet. What is the distance traveled by the bird, if its speed is 176 kmph?
Answers
Answer:
the distance traveled by the bird = 3.2 km
Step-by-step explanation:
Here more interesting thing is for how much time bird fly
Bird fly for the same time as A & B walked
A & B are at a distance of 800 m = 0.8 km
their relative speed = 20 + 24 = 44 km/hr
Time Taken = 0.8/44 = 1/55 hr
Bird Speed = 176 km /hr
Distance covered by bird = 176 * 1/55
= 16/5
= 3.2 km
the distance traveled by the bird = 3.2 km
Answer:
3200 m
Step-by-step explanation:
Given A & B are at a distance of 800 m. They start towards each other at 20 & 24 kmph. As they start, a bird sitting on the cap of A, starts flying towards B, touches B & then returns towards A & so on, till they meet. What is the distance traveled by the bird, if its speed is 176 kmph?
A and B are at a distance of 800 m, also the bird flies at the same time . So time taken by A and B together, so the distance covered will be in the ratio of their speeds.
Now ratio of speed will be (20 + 24) = 44 : 176
= 1 : 4
So if A and B cover 800 m the bird will cover 800 x 4 = 3200 m
