a man climbs up a slope at a speed of 60km per hour and descends it at the speed of 90km per hour. if the distance covered each way is same. find the average speed for the entire journey.​

  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).

c - they will have the same distribution

step-by-step explanation:

this is the only one that could make sense. : )

answer: x=3 and y=4
