The correct answer to the question is : 2.976 miles/hour.
CALCULATION:
As per the question, the distance travelled by the bird X = 1000 miles.
The time taken by the bird to cover that distance t = 2 weeks.
= 2 × 7× 24 hours
= 336 hours
We are asked to calculate the speed of the bird.
The speed of the bird is calculated as -
speed v = [tex]\frac{distance}{time}[/tex]
= [tex]\frac{1000}{336}\ miles/hour[/tex]
= 2.976 miles/hour [ans]
Hence, the velocity of the bird is 2.976 miles/hour.
