The hours it takes Kristen to travel the same distance Marian travelled is 19.5 hours.

The average speed of Marian is 65 miles per hour for 15 hours. Therefore, her distance travelled can be calculated as follows:

speed = distance / time

Therefore,

distance = time × speed

distance = 15 × 65

distance = 975 miles

Kristen travelled at an average speed of 50 miles per hour. Kristen covers the same distance with Marian. Therefore, the hours it takes Kristen to travel the same distance Marian travelled can be calculated as follows:

speed = distance / time

time = distance / speed

time = 975 / 50

time = 19.5 hours

The type of mood that the above setting from Jekyll and Hyde creates is a creepy one. This is evident from the use of words like "sinister block", "gable on the street", and "showed no window", all of which foreshadow an eerie presence to the reader.

A setting might be a true time and place, or it can be a fictional universe and an unknown time. Along with the physical surroundings that provide a backdrop for the action, the setting also refers to the climatic conditions, the weather, and the social and cultural context. An account's exposition reveals the setting.

What happen if I don't do end of the year finals​
Alex73 [517]

Finals are often 20% to 40% of your final grade. If your class require that you take a final and you don’t take it, you’d get a 0.. which would put a pretty big dent in your average. If you missed all of your finals, it would most likely hurt your GPA as well.
