April and May extracted oil from lime peel. They used the same solvent with the same concentration and amount and the same numbers and equal size of limes. Also, the amount of time spent on the extractions was equal. However, April obtained more oil than May. Why did this happen?

6.4 cm (max) - 25 cm (min)

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
