What value of x completes the table?
1.2
1.5
3.6
13.3

Answer 1

1.2 Inches, It moves 0.3 inches in 1 hour so if in 1 hour it moves 0.3 and in 2 0.6 and in 3 0.9 so in 4 hours it will move 1.2 inches

Answer 2

Answer:

The correct option is 1.

Step-by-step explanation:

It is given that the glacier is moving at a rate of 0.3 inches every hour. It means the average rate of change is 0.3.

Let d is the total moved distance of glacier and t is number of hours. Then the total moved distance of glacier after t hours is defined as

$d=0.3t$

At t=1,

$d=0.3(1)=0.3$

At t=2,

$d=0.3(2)=0.6$

At t=3,

$d=0.3(3)=0.9$

At t=4,

$d=0.3(4)=1.2$

Total moved distance of glacier after 4 hours is 1.2 inches.

The value of x is 1.2. Therefore the correct option is 1.
