A car traveled a total distance of 385 km. How long did it travel if its average speed was 55 kph?

7 hours

Step-by-step explanation:

385/55 =7

.

...

6.5 hours

Step-by-step explanation:

to find time the equation is T=D/S

T= time D=distance S=speed

then you input what you know so

T=385/55

then I rounded to 6.5 hours

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).

logv3(x+2)=1

rewrite in exponential form:

logb(x) = y is equal to b^y =x

b = 3, y = 1

now solve for x:

3^1 = x+2)

x = 3-2

x = 1

see the picture for the graph.
