Answer:
Step-by-step explanation:
Graham’s altitude after t minutes = 14,040 - 50t feet.
Max’s altitude after t minutes = 12,500 + 20t
When they are at the same altitude,
14,040 - 50t = 12,500 + 20t
1,540 = 70t
t = 22
They are they same altitude after 22 minutes.
:::::
160 + 3t = 195 - 2t
5t + 35
t = 7
They are the same weight after 7 weeks.
