the average rate of change is 4/3
Explanation:
Function: f(x)=4/3x + 8
rewriting in the form of equation of line: y = mx + c
m = slope = rate of change
c = intercept
Comparing with the given function:
m = 4/3
c = 8
Hence, the average rate of change is 4/3
Answer:
Step-by-step explanation:
The journey began at 10:00 . The distance moved from this time is 110 miles. The cruise control is always set at 55 miles per hour. This means 110 miles was covered driving at a speed of of 55 miles per hour.
Speed = distance/ time
Time = distance/speed
Time at which 110 miles was covered will be 110/55 = 2 hours
So at 12:00 o'clock, I have covered 110 miles.
I then get hungry and take an hour break to eat lunch. After eating lunch for one hour, I resumed the journey at 13:00.
I drove 165 miles after the break.
The time taken to drive 165 miles
= distance / speed
= 165/55 = 3 hours
Total hours spent is 2 hours before the break + 1 hour break + 3 hours after the break = 6 hours
The trip ended at 16:00
