The distance the bird has flown by the time Alice and Bob meet is 40 feet.
Given that the distance between Alice and Bob is 1000 feet and their running speed is 10 feet per second and the speed of bird is 20 feet per second.
Distance equals speed multiplied by time.
Distance between Alice and Bob=1000 feet.
Distance between the bird and Bob=1000 feet.
Speed of Alice and Bob=10 feet per second.
The combined speed of Alice and Bob=20 feet per second.
Since the two are running directly toward each other the distance each will cover at the meeting point is 50 feet (1000/20)
The time covered at the meeting point=20 second (1000/50)
Speed of the bird=20 feet per second.
The distance covered by the bird towards Bob at their meeting point is 40 feet(20 feet*20 seconds).
Hence the distance the bird has flown by the time Alice and Bob meet is 40 feet.

Answer:
The angle of rotation is 214°.
Step-by-step explanation:
Formula for arc length:
The length of arc is the product of radius and the central angle ( in radian).
L= rθ
L= Length of arc
r= Radius
θ= Central angle (in radian).
Here L= 280 feet and diameter =150 feet.
Radius feet =75 feet
L= rθ
radian.
We know that,
π radian= 180°
= 214°
The angle of rotation is 214°.
