It is three hours. If you go to a calculator, and add 55 + 35 you get $90. So, you keep adding +35 until you get your answer, and how many times you put (+35) is how many hours.

He was there for 3 hours cause 3 x 35 = 105 but 105 + 55 = 160

Answer:

A. 525 feet

Step-by-step explanation:

If every hour their altitude increased by 135 then their would be an increase of 675 (135 × 5) after 5 hours. To find their altitude 5 hours earlier then you would subtract 675 from their current altitude. 1,200-675=525 feet
