Answer:
Air travels 6,920 meters in 20 seconds.
Step-by-step explanation:
If in one second air travels 346 meters, and you want to find out how many meters air travels in 20 seconds, then just multiply 346 by 20.
All you do is subtract what John is spending from the amount he has. 20.43-15.39= $5.04
180 seconds is 3 minutes. If you divide 156 by 3, you will get 52. If you are looking for 2 minutes, you have to multiply 52 by 2. The answer is 104 revolutions in 2 minutes.
