#1) A hot air balloon is at an altitude (height) of 113.2 meters. The balloon's altitude decreases by 10.8 meters every minute.
Minchanka [31]

Answer:

5min

Step-by-step explanation:

First form yourself an equation,  113.2-10.8x ≤70

Now begin to work it out

*113.2-10.8(1) ≤70 (instead of x, put a number, this will be how many minutes

1~ 102.4 is not less than or equal to 70, so we repeat this process

2~ 91.9

3~81.1

4~70.3 this is not the answer because even though its at 70 there is still a .3 so we keep going,

5~59.5

59.5 is ≤ 70, so the answer is 5 minutes

P.S. don't believe me? that's okay, use the formula, plug in five to see for yourself

i hope this helps ;)
