Verified Answer :

Answer:

- the rate of change is 2.5 km per second.

- the rate of change is 150 km per minute.

Step-by-step explanation:

Answer:

The rate of change is 2.5 km per second.

The rate of change is 150 k per minute.

Step-by-step explanation:

The table below shows the distance, d of a spaceflight above the earth in time, t.

Time (t)                   Distance (d)

8 seconds               20 km

34 seconds             85 km

2 minutes                300 km

5 minutes                 750 km

From the given table we calculate the distance covered in 1 second.

In 8 second distance covered = 20 km

in 1 second distance covered = 20/8 = 2.5 km

in 1 minute (60 seconds) distance covered = 2.5 × 60 = 150 km

Therefore, statement 1 and 4 are the correct statements.
