Name one process which remove car bon iv oxide from the atmosphere and fixes hydrospheric nitrogen as nitratev in the soil​

idk what is it? is this a question that you know the answer or u dont

answer;

18.5 seconds

explanation;

velocity is distance covered per unit time; it is given by displacement divided by time.

thus; time = displacement/velocity

total time = total displacement/velocity

total distance = 5000 meters south

total time = 5000/4.5

                  = 1111.11 seconds

but; 1 minute = 60 sec

thus; 1111.11 /60

                = 18.51 seconds

thus; the time taken is 18.5 seconds
