The table shows the times it took different animals to cover various distances.
MOTION OF ANIMALS
Animals Distance (km) Time (h)
Gray fox 73 1.05
Gazelle 68 0.85
Rabbit 70 1.25
Cheetah 85 0.75
Giraffe 60 1.15
Antelope 93 0.95
Which animal's speed is the greatest?
a
gazelle
b
cheetah
c
gray fox
d
rabbit
To determine which animal has the greatest speed, we can calculate the speed for each animal using the formula speed = distance/time. Comparing the speeds of each animal, we can determine which animal has the greatest speed.
The speeds for each animal are as follows:
Gray fox: 73 km / 1.05 h = 69.52 km/h
Gazelle: 68 km / 0.85 h = 80 km/h
Rabbit: 70 km / 1.25 h = 56 km/h
Cheetah: 85 km / 0.75 h = 113.33 km/h
Giraffe: 60 km / 1.15 h = 52.17 km/h
Antelope: 93 km / 0.95 h = 97.89 km/h
Based on these calculations, the cheetah has the greatest speed with a speed of 113.33 km/h. Therefore, the correct answer is b) cheetah.
