Answer:</h2>
His average speed on the return drive is:
50 mph
<h2>
Step-by-step explanation:</h2>
Let d be the distance from home to the place of his job interview.
Let s be the average speed when he drive to his job interview.
Now, it is given that:
It took Gustavo 5 hours to drive to a job interview.
We know that distance is the product of speed and time.
i.e.
Hence, we have:
Also,
On the way home, he was able to increase his average speed by 20 mph and make the return drive in only 3 hours.
His average speed back home is: s+20
and his time is: 3 hours
Hence, we have:
From equation (1) and equation (2) we have:
Hence, his average speed on the return drive is: s+20
= 30+20
= 50 mph
If the measure of central angle is 3π /4 radians, then the area off the shaded sector is 96π square units
The radius of the circle = 16 units
The central angle of the shaded region = 3π /4 radians
The area of the sector = (θ/ 360) × πr^2
Where θ is the central angle of the sector
r is the radius of the sector
Substitute the values in the equation
The area of the sector = ((3π /4) /360) × π × 16^2
Convert the radians to the degrees
= (135/360) × 256π
Multiply the terms
= 96π square units
Hence, the area of the shaded sector is 96π square units
The complete question is
