Question

two species of birds are being compared. Species A can fly 18.9 miles in 42 minutes, while species b can fly 20.3 miles in 58 minutes. Which species is the slower, and at what speed can it fly?

Answer 1

Answer:

Species B is slower and flies at a rate of 0.35 miles per minute.

Step-by-step explanation:

We have been given that species A can fly 18.9 miles in 42 minutes, while species b can fly 20.3 miles in 58 minutes.

$\text{Speed}=\frac{\text{Distance}}{\text{Time}}$

$\text{Speed of species A}=\frac{\text{18.9 miles}}{\text{42 minutes}}$

$\text{Speed of species A}=\frac{\text{0.45 miles}}{\text{minute}}$

$\text{Speed of species B}=\frac{\text{20.3 miles}}{\text{58 minutes}}$

$\text{Speed of species B}=\frac{\text{0.35 miles}}{\text{minutes}}$

Therefore, the speed of species B is slower and it can fly 0.35 miles per minute.

Answer 2

Species A: 18.9 miles / 42 minutes = 0.45 miles per minute
Species B: 20.3 miles / 58 minutes = 0.35 miles per minute
Therefore, species A is faster and flies at a speed of 0.45 miles per minute
(27 mph)
0.45 x 60 = 27 mph
