1. A motorboat travels 196 meters in 20 seconds. What is the motorboat's unit rate of speed? Step1. Write equivalent ratios.
The boat's rate of speed is 196m/20 secs.
Let X represent the unknown. The second ratio is: xM/1 sec.

Step2. set up and solve a proportion.

19/20 = X/1

196 . = 20 .
=
X =

The unit rate meters per second.

The equation shown below represents function f. f(x)= -2x+5 the graph shown below represents function g. which of the following statements is true? a. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is less than the y-intercept of function g. b. over the interval [2, 4], the average rate of change of f is greater than the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. c. over the interval [2, 4], the average rate of change of f is the same as the average rate of change of g. the y-intercept of function f is greater than the y-intercept of function g. d. over the interval [2, 4], the average rate of change of f is less than the average rate of change of g. the y-intercept of function f is the same as the y-intercept of function g.
