Answer:
Class width = max value-min value/# of classes
Class width is the difference between two consecutive lower class limits (or two consecutive lower class boundaries) in a frequency distribution.
The lower (and upper) class limits are the smallest (and largest) numbers that can belong to the different classes.
The lower (and upper) class limits are the smallest (and largest) numbers that can belong to the different classes.
The first lower class limit is approximately 90, and the second lower class limit is approximately 120.
Determine the distance between them.
120−90=30
Therefore, the class width is 30.
The approximate lower class limit of the first class is the first approximate lower class limit found above (approximately 90). The upper class limit of the first class is approximately equal to the second lower class limit, 120.
Therefore, the approximate lower and upper class limits of the first class are 90 and 120, respectively.

Given question is in incorrect format as it is a mixture of two questions. The two questions are as follows :
(1) The theory of ______ incorporates the ideas of both seafloor spreading and continental drift into a unified model.
(2) The age of the sea floor ______ away from the ocean spreading centers.
Answer:
1- Plate tectonic
2- Increases
Explanation:
The plate tectonic theory describes the movement of the tectonic plates from one place to another due to the generation of convection current in the mantle. It is possible due to the heat supplied from the interior of the earth. It is the key to the understanding of both the seafloor spreading and the continental drift.
The seafloor spreading takes place in a divergent plate boundary, forming a mid-oceanic ridge, through which the magma from the interior of the earth comes out at the seafloor. The rocks that are deposited and formed in and around this ridge are the geologically youngest rocks. And as one travels away from the mid-oceanic ridge, the age of the seafloor increases.
