Find the elapsed time. Carol drove to her sister’s house. She drove from 6:38 to 9:45. How long did she drive?
A. 2h 53 min
B. 3h 7 min
C. 3h 53 min
D. 4h 7 min

( B) explination

Step-by-step explanation:

6:38 so i got to a easy number to just add easier

+0.22

7:00. -9:45=2.45 so 45 is 3/4 of an hour so there is 1 left so 15=1/4 of an hour so 2.45

+0.15

3:00

so 22-15=7 so she drove 3 hours and 7 minutes :)

the formula of a slope:

from a table we have

substitute:

the slope of f(x) is -1.

the graph of funcfion g(x) is a horizontal line. the slope of a horizontal line is equal 0. therefore the slope of g(x) is 0.

-1 < 0
