Answer:
3.08 km/h.
Step-by-step explanation:
We know that,
Ali traveled at a speed of s km/h for 2.5 hours.
Let d be the distance and t be the time.
...(1)
On his return journey, he increased his speed by 4 km/h and saved 15 minutes. So, distance is d and times is t-15.
...(2)
From (1) and (2), we get
Put t=40 in (1).
So, t=40 and d=100.
Now,
Total distance = d + d = 100 + 100 = 200
Total time = t + t - 15 = 40 + 40 - 15 = 65
So, the average speed is
Therefore, the average speed is 3.08 km/h.

Answer:
The best approximation for the input value when f(x) = g(x) is x = 1.5.
Step-by-step explanation:
The function f(x) passes through the points (-3,1) and (0,1) and the point (1.5,1).
Therefore, the line has equation y = 1.
Now, the function g(x) passes through the points (0,-1), (1.5,1) and (3,3) points.
Therefore, the function g(x) crosses the line y = 1 at the point (1.5,1).
Hence, the best approximation for the input value when f(x) = g(x) is x = 1.5. (Answer)
