Answer:

After 4 minutes

Step-by-step explanation:

Balloon 1

  • Initial position = 10 m
  • Rise rate = 15 m/min

Balloon 2

  • Initial position = 150 m
  • Drop rate = 20 m/min

Time required for the balloons to meet = x

After x minutes the first balloon will be at position:

  • 10 + 15x

And the second balloon will be at position:

  • 150 - 20x

Since they meet after x minutes, their position must be same:

  • 10 + 15x = 150 - 20x
  • 15x + 20x = 150 - 10
  • 35x = 140
  • x = 140/35
  • x = 4 minutes

So the balloons will meet after 4 minutes
