Answer 1

The table that shows the relationship between the time in seconds, x, and the height of the balloon in feet, y is H. This table shows that for every 10 seconds that pass, the height of the balloon increases by 20 feet. This is consistent with the information given in the question that after 5 seconds the height of the balloon is 20 feet and it continues to rise at the same rate.
