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 slower, and at what speed can it fly?
Species A is slower, and it can fly 0.35 miles per minute.
Species A is slower, and it can fly 0.45 miles per minute.
Species B is slower, and it can fly 0.35 miles per minute.
Species B is slower, and it can fly 0.45 miles per minute.

Answer 1

To determine which species is slower and their respective speed, we'll first convert the distances and times into speeds measured in miles per minute.

**For Species A:**
- Distance: 18.9 miles
- Time: 42 minutes

Speed of Species A = Distance / Time = 18.9 miles / 42 minutes = 0.45 miles per minute.

**For Species B:**
- Distance: 20.3 miles
- Time: 58 minutes

Speed of Species B = Distance / Time = 20.3 miles / 58 minutes = 0.35 miles per minute.

Now, comparing the speeds:
- Species A: 0.45 miles per minute
- Species B: 0.35 miles per minute

Species B is slower, and it can fly at a speed of 0.35 miles per minute.

Thus, the correct answer is:
**Species B is slower, and it can fly 0.35 miles per minute.**
