Question

A hot air balloon is launched at Kirby park, and it ascends at a rate of 7200 feet per hour. at the same time, a second hot air balloon is launched at Newman Park, and it ascends at a rate of 4000 feet per hour. both of the balloons stop ascending after 30 minutes. the diagram shows the altitude of each park. are the hot air balloons ever at the same height at the same time?

Answer 1

So 30 minutes=1/2 hour


7200 per hour
7200 times number of hours=height of first hot air ballon

4000 per hour
4000 times numbe rof hours=height of second ballon


1/2 hour

7200 times 1/2=3600


4000 tiemes 1/2=2000


they will never be since the first one will acent much faster that the other
