Question 915935: Johnny is in a hot air balloon that is at 900 feet and rising 5 ft per hour. Susie is in a hot air balloon that is at 1240 feet and is falling at 12 ft per hour.
a) how long will it be until Johnny and Susie are at the same height?
900+5n=1240-12n
-900 +12n -900 +12n
17n=340
17n/17=340/17
n=20
b) Use the equation and answer from part a to determine what height they will be when they meet. ????

900+5*20=1240-12*20
900+100=1240-240
1000=1000
The height they meet at is one thousand feet.
