Speed (m/s) = distance (metres) ÷ time (seconds)
For Track 1: 0.2 ÷ 2 = 0.1m/s
For Track 2: 0.2 ÷ 2 = 0.1m/s
For Track 3: 0.6 ÷ 6 = 0.1m/s
For Track 4: 0.4 ÷ 6 = 0.07m/s
The train on Track 4 had the slowest speed because it's got the shortest speed and it's covering less distance per second therefore it is slower.

Global warming will cause see levels to rise since a lot of water is stored in ice sheets which will melt. All of the melt water will end up in the ocean causing sea levels to rise.
I hope this helps. Let me know if anything is unclear.
Answer:
In analytical chemistry, the titrant is a solution of known concentration that is added (titrated) to another solution to determine the concentration of a second chemical species. The titrant may also be called the titrator, the reagent, or the standard solution.
hope it helps (^^)
