Answer:
£978
Step-by-step explanation:
i did use a calculator so i don't know if this is wrong or not, sorry if it is.
Hi there,
2400 + 1632 = 4032
3 * 192 = 576
4032 - 576 =>
3532 - 76 =>
3532 + 24 - 76 - 24
3556 - 100
3456
3456 / 576 => 6
Therefore, 6 hours of sprayer work
Hope this helps!
Sincerely,

<u>Given</u>:
The distance (in kilometers) Dora hiked is modeled as a function of time.
We need to determine the average rate of change in distance hiked, measured in kilometers per hour, between 8:30 am to 1:30 pm.
<u>Average rate of change:</u>
Let us write the time and the distance hiked in coordinates for the time 8:30 am and 1:30 pm.
Thus, the coordinates are (8.30, 4) and (1,12)
The average rate of change can be determined using the formula,

Substituting the points (8.30, 4) and (1.30,12), we get;



Rounding off to the nearest whole number, we get;

Therefore, the average rate of change is -1.
