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

The correct option is 1.

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.
