Answer: It will take 8 minutes to be on same height.
Step-by-step explanation:
Let x= Time taken to be at same height.
The first is 130 feet high and is rising at a rate of 7 feet per minute.
Height = 130+7x
The second is 226 feet high and is descending at a rate of 5 feet per minute.
Height = 226-5x
According o the question,
[tex]130+7x=226-5x\\\\\Rightarrow\ 7x+5x=226-130\\\\\Rightarrow\ 12x = 96\\\\\Rightarrow\ x=\dfrac{96}{12}\\\\\Rightarrow\ x=8[/tex]
Hence, it will take 8 minutes to be on same height.
