Solid ehunk 2. Select the DATA tab and look at the graph What do the blue curve and the yellow curve represent?
The Skecuve represents
The yellow cuve represents
3 What is the tal temperature of the top flask?
Bottom dask?

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
