hot air balloons
-dallation for
a hot air balloon is a "lighter-than-air" aircraft consisting of a
bag, called an envelope, which contains heated air. hot air balloons
fly because hot air rises. by heating the air inside the balloon with
the burner, it becomes lighter than the cooler air on the outside.
this causes the balloon to float upwards. if the air is allowed to
cools, the balloon begins to slowly come down.

a hot air balloon pilot is flying a balloon 560 meters above the
ground. when landing, the balloon descends at a rate of about 8 meters per second.
1. would you use a positive or negative integer to represent the balloon's rate of descent?
write the integer and explain your reasoning.
2. complete the table below to determine how far the balloon would descend after 5 seconds.
time (s)
distance (m)
-
3. write an addition expression to represent the total change in the balloons height after 5
seconds.
what is the sum?
4. multiplication is defined as repeated addition. rewrite your above expression as an
equivalent multiplication expression.
5. predict the value of -8(5).
6. how long will it take for the balloon to land?
