The bottom of a garage door is 2.8 meters above the ground. When a bottom is pushed, the door moves down at rate of 0.6 meter per second. Which equation can be solved to find t, the time in seconds it takes the door to close completely?

A. 0.6 - 2.8t = 0
B. 2.8 -0.6t = 0
C.0.6 +2.8t=0
D. 2.8 + 0.6t=0

12

Step-by-step explanation:

Select the GCF of these numbers. 48 and 60

We find the GCF of 48 and 60 using factorisation method.

The factors of 48 are: 1, 2, 3, 4, 6, 8, 12, 16, 24, 48

The factors of 60 are: 1, 2, 3, 4, 5, 6, 10, 12, 15, 20, 30, 60

Then the greatest common factor is 12.

Therefore, the greatest common factor of 48 and 60 is 12
