Explanation:
Kelly drives 448 miles on the highway to visit her cousin. She uses cruise control to drive at a constant speed . Kelly travels 192 miles in the first 3 hours. At that rate, how long will the trip take?
Solution:
Speed is the rate of change of distance with respect to time. The speed of an object tells us how fast the object is. Speed is the ratio of distance travelled to total time take, it is given by the formula:
Speed = distance / time
From the question, Kelly travels 192 miles in the first three hours, hence her speed is:
Speed = distance / time
Speed = 192 miles / 3 hours = 64 miles per hour
At constant speed, the time taken to drive 448 miles is:
Speed = distance / time
64 miles per hour = 448 miles / time
time = 448 miles / 64 miles per hour
time = 7 hours

Answer:
B. Before they were dismissed from school, the children collected their belongings from their lockers and put on their coats.
Explanation:
Sentence fragments are fragments of sentences that are together but not complete as a sentence. They are more like dependent clauses, with no meaning, and also doesn't make a full meaningful sentence. Sometimes, different punctuation may be required to make them into complete sentences.
Among the given sentences, option B is a complete sentence with correct punctuation and sentence structure.
The other options are sentence fragments as they either are incomplete sentences or they need a change in the punctuation used.
Like in sentence A, the period/ full stop between "lockers" and "And" should be removed. And change the "A" into "a".
In sentence C, the same case with the position of the period. Removing the period after "school", change it into a comma and changing the capital "T" from "The" to "t".
Sentence D also has the same error- the period after "belongings" and changing "F" into "f" of "From".
Thus, the <u>correct answer is sentence B.
</u>
<span>The word help is incorrect because it has an error in subject-verb agreement.
Subject verb agreement happens when the subject of the verb agrees with the correct form of the verb. The subject of the verb help is it". "It" is a third person singular pronoun. </span>In order to make help agree with the subject "it", and -s is necessary. It should say "...and it helps to build...".<span>
Often when a verb agrees with a singular third person pronoun, it is necessary to add -s to the end of the verb. For example, It runs, It walks, It smiles. When you use first or second person pronouns there is no -s, as in: I run, You walk, I smile. </span>
