A red ballon starts at 7 meters off the ground and rises at 3 meters per second. A ballon starts at 12 meters off the ground and rises at 2 meters per second. Write and solve an equation to determine when the balloons are at the same height
Let x be the no. of seconds it takes for the balloons to be at the same height. 7+3x = 12+2x Deduct both sides by 2x. 7+x = 12 Deduct both sides by 7. x = 5 Ans: It will take 5 seconds for the balloons to be at the same height.
