A moterboat that ravels with a speen of 20km/hour in still water has traveld 20 km against the current and 180km with the current having spent 8 hours on the entire trip find the speed of the current of the riveer. plz help ill give brainliest

160 is the answer

please give me the brainliest

  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).

i you goofed up when writing this, because hnot is not a word minusf is not either. i cannot answer   because of that.
