Question

HELP QUICKLY The graph shows the total number of hours Katrina worked over a 10-day period.

Answer 1

Answer:

Day 7 - 8

Step-by-step explanation:

We can calculate the maximum work she did in each interval by finding the difference between the y axis limits for each day.

This is also observed by the steepness of the graph, which is steepest for the interval between 7- 8 hours .

From day 1 to day 2 she worked 3 hours

From day 4 to 5 she worked 0 hours

From day 7 to 8 she worked 6 hours

From 9 to 10 she worked zero hours.

Hence, the maximum work she did was from day 7 to 8

Hope this helps

Answer 2

Answer:

Option C From day 7 to day 8

Step-by-step explanation:

The given graph shows the total number of hours Katrina worked over the period of 10 days.

Now we will calculate the number of hours worked by Katrina for every given options in the question.

Option A - From day 1 to day 2

Katrina worked (6 - 3) = 3 hours

Option B - From day 4 to day 5

Katrina worked (12-12) = 0 hours between the period of 4 to 5 days

Option C - From day 7 to day 8

Katrina worked (18-12) = 6 hours

Option D - From day 9 to day 10

Katrina worked ( 18 - 18) = 0 hours so she took the rest.

According to this, options C represents the work done for maximum hours in one day interval.
