12 km / 3hrs = 4 km/hr.
The final answer is 4 km/hr.
Hope this would help~~
Let us set up a proportion.

12/3             Amount he traveled in 3 hours was 12 kilometers.

12/3 = x/1     We are looking for how many kilometers per hour (x)

Cross multiply

12/3 = x/1
12*1 = x*3

12 = 3x

3x = 12           Solve for x

3x/3 = 12/3      Divide both sides by 3.
x = 12/3
x = 4            X equals 4

Final answer:- Andrew traveled 4 kilometers per hour.
