To find out which animal's speed is the greatest, we need to calculate the speed of each animal using the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
We'll calculate the speed for each animal.
-
Gray fox: \[ \text{Speed} = \frac{73 \text{ km}}{1.05 \text{ h}} \approx 69.52 \text{ km/h} \]
-
Gazelle: \[ \text{Speed} = \frac{68 \text{ km}}{0.85 \text{ h}} \approx 80 \text{ km/h} \]
-
Rabbit: \[ \text{Speed} = \frac{70 \text{ km}}{1.25 \text{ h}} = 56 \text{ km/h} \]
-
Cheetah: \[ \text{Speed} = \frac{85 \text{ km}}{0.75 \text{ h}} \approx 113.33 \text{ km/h} \]
-
Giraffe: \[ \text{Speed} = \frac{60 \text{ km}}{1.15 \text{ h}} \approx 52.17 \text{ km/h} \]
-
Antelope: \[ \text{Speed} = \frac{93 \text{ km}}{0.95 \text{ h}} \approx 97.89 \text{ km/h} \]
Now, let's compare the speeds:
- Gray fox: 69.52 km/h
- Gazelle: 80 km/h
- Rabbit: 56 km/h
- Cheetah: 113.33 km/h
- Giraffe: 52.17 km/h
- Antelope: 97.89 km/h
The animal with the greatest speed is the Cheetah.
The answer is: b) Cheetah.
