To determine which animal has the greatest speed, we can calculate the speed of each animal using the formula:
\[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]
Let's calculate the speed of each animal:
-
Gray Fox \[ \text{Speed} = \frac{73 \text{ km}}{1.05 \text{ h}} \approx 69.52 \text{ km/h} \]
-
Gazelle \[ \text{Speed} = \frac{68 \text{ km}}{0.85 \text{ h}} \approx 80.00 \text{ km/h} \]
-
Rabbit \[ \text{Speed} = \frac{70 \text{ km}}{1.25 \text{ h}} = 56.00 \text{ km/h} \]
-
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: ~80.00 km/h
- Rabbit: 56.00 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 at approximately 113.33 km/h.
Therefore, the answer is:
d) cheetah
