EXTRA CREDIT. The rate at which an object moves is its speed. If a horse walked 50m in 68s, cantered 150m in 35s, and galloped 300m in 22s, what
would its average speed be? Show your work! Help ASAP

Average speed is total distance divided by total time.

Total distance is 50 m + 150 m + 300 m = 500 m
Total time is 68 s + 35 s + 22 s = 125 s

Average speed is 500 m / 125 s = 4 m/s

C) the increase in atmospheric pressure pushes the walls of the balloon outward thus making it  is the answer.hope i you.

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.
