Average speed is calculated by dividing the total distance travelled by the time interval. For example, someone who takes 40 minutes to drive 20 miles north and then 20 miles south (to end up at the same place), has an average speed of 40 miles divided by 40 minutes, or 1 mile per minute (60 mph).

The average speed is the distance travelled divide by the time taken: Average speed = Distance travelled time taken

Step-by-step explanation:

Scale factor red to blue meaning 42 to 7

42÷7=6

Scale factor is 6

Perimeter of the blue quadrilateral = ?

If perimeter of red = 204

Then we use this following proportion

$204 \div 42 = x \div 7$

$\frac{204}{42} = \frac{x}{7}$

Then we cross multiply

42x=7×204

42x=1428

x=34

Area of the blue quadrilateral = ?

If area of the red quadrilateral = 2880

Then we use the following proportion

$2880 \div 42 = x \div 7$

$\frac{2880}{42} = \frac{x}{7}$

Then we cross multiply

42x=2880×7

42x=20160

x=480

Overtime pay definition

Marizza181 [45]

In your work field, depending on the comapny, there are a certain amount of hours you can work before going into overtime. Overtime pay is when you work over the minimum corperate set hour base line. Which if you pass that certain number, you get pay and a half. Which basically means your regular hour pay, but another half of it. So say you're making $9 and hour. If you go into overtime, you'd be making $13 an hour. But only in thos overtime hours. So if you worked say 7 hours overtime, you'd make $91 just in those 7 hours.
