Question

right after takeoff, a hot air balloon ascends at a constant rate of 400 feet per minute. complete the table to show the hot air balloon’s elevation after takeoff. time since takeoff (min) | elevation (ft) 0 | 0 1 | □ 2 | □ 3 | □ 4 | □

Explanation:

Step1: Understand the relationship

The balloon ascends at 400 feet per minute. So elevation = rate × time.

Step2: Calculate for 1 minute

Time = 1 min, Elevation = \( 400 \times 1 = 400 \) feet.

Step3: Calculate for 2 minutes

Time = 2 min, Elevation = \( 400 \times 2 = 800 \) feet.

Step4: Calculate for 3 minutes

Time = 3 min, Elevation = \( 400 \times 3 = 1200 \) feet.

Step5: Calculate for 4 minutes

Time = 4 min, Elevation = \( 400 \times 4 = 1600 \) feet.

Answer:

For time 1 min: 400 ft
For time 2 min: 800 ft
For time 3 min: 1200 ft
For time 4 min: 1600 ft
