a) 
The average speed is equal to the ratio between the total distance (
and the total time taken (
):
the distance travelled by the trucker in the first 3 hour can be written as the time multiplied by the velocity:
So the total distance is
The total time is equal to the first 3 hours + the time taken to cover the following 20 miles in the city:
So, the equation can be rewritten as:
b) 0.50 h (half a hour)
Since we know the value of the average speed, 
, we can substitute it into the previous equation to find the value of 
, the time the trucker drove in the city:
Answer:
A) 75%
B) 76
Step-by-step explanation:
A) 39/52=0.75=75%
B)80x0.95=76
Is there a question...or...?
Answer:
108 since in order to find out the maximum amount, we have to find the volume of the full pan, which is found by the formula shown below:
Vbrownie batter=L×W×H=9×8×1.5=108cubic inches
