Step-by-step explanation:

Joe's climbing rate is not constant

3 × 2 = 6

8 × 1.5 = 12

12 × 1.1666666667 = 14

Time when climber reaches 30ft is unknown because climbing rate is not constant

Zas's climbing rate is 2.5

2 × 2.5 = 5

4 × 2.5 = 10

12 × 2.5 = 30

At 12 seconds, Zas reaches 30 feet.

Stephen's climbing rate is 4

2 × 4 = 8

4 × 4 = 16

6 × 4 = 24

30 ÷ 4 = 7.5

7.5 × 4 = 30

At 7.5 seconds, Stephen reaches 30 feet.
