A helicopter altitude changes by -28 1/8 ft in 3 3/4 s. What is the average change in the helicopters altitude each second?

- 7 1/2 feet

Step-by-step explanation:

From the question, we are informed that a helicopter altitude changes by -28 1/8 ft in 3 3/4 s. The average change in the helicopters altitude each second will be gotten by dividing -28 1/8 by 3 3/4. This will be

= -28 1/8 ÷ 3 3/4

= -225/8 ÷ 15/4

= -225/8 × 4/15

= -15/2

= -7 1/2

The average change in the altitude each second is - 7 1/2 feet
