If a balloon rises 700 m in 3 minutes, what is it's average speed in km/h

What could explain what happened when the time was equal to 120 minutes

100 points, hi, i’m not sure how to get the equation from the graph and table.

If $740 is invested at an interest rate of 11% per year and is compounded continuously, how much will the investment be worth in 7 years? use the continuous compound interest formula a = pert.
