Answer:
7 hours
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
1st person: is a mode of storytelling in which a storyteller recounts events from their own point of view using the first person such as "I", "us", "our" and "ourselves".
2nd person: is often used for giving directions, offering advice, or providing an explanation. This perspective allows the writer to make a connection with his or her audience by focusing on the reader. Second person personal pronouns include you, your, and yours.
3rd person: the narrator exists outside of the story and addresses the characters by name or as "he/she/they" and "him/her/them." Types of third person perspective are defined by whether the narrator has access to the thoughts and feelings of any or all of the characters.
I’m not sure about the last question like I don’t know what it is asking but yeah here’s this ¯\_(ツ)_/¯
