=C=4km=C=4km/h/h

Explanation:

The gazelle is travelling at 2km2km/0.5hours/0.5hours. One half hour is equal to 0.50.5 hours. Speed is measured as kmkm/h/h. To go from 0.5 hours to 1 hour you need to multiply it by 2, 0.5*2=10.5⋅2=1. Because you multiply the time by two, you need to multiply the distance by 2. 2*2=42⋅2=4.

Therefore the speed of the gazelle is 4km/h, and the correct answer is C.

I hope I helped!
