Answer:
40+2s=60-3s
Step-by-step explanation:
The red balloon starts 40 feet off the ground and rises 2 feet per second. This means the height of the red ballon is 40+2s.
The blue balloon starts 60 feet off the ground at starts falling 3 feet per second. This means the height of the blue balloon is 60-3s.
Because we want to find out when the balloons will be the same height, we set them equal to each other.
40+2s=60-3s
