Average Speed Puzzle Answer Key

There are three chief types of boilerplate problems ordinarily encountered in school algebra:
Boilerplate (Arithmetic Mean)
Weighted Boilerplate and
Boilerplate Speed.

How to calculate Boilerplate Speed?

The following diagram shows the formula for average speed. Curlicue downward the page for more examples and solutions on calculating the average speed.

Examples Of Boilerplate Speed Issues

Instance:
John drove for iii hours at a rate of 50 miles per hr and for ii hours at 60 miles per hour. What was his boilerplate speed for the whole journey?

Solution:
Step 1: The formula for distance is

Distance = Rate × Time
Total distance = 50 × 3 + 60 × 2 = 270

Stride 2: Total fourth dimension = 3 + 2 = 5

Step 3: Using the formula:

Reply: The average speed is 54 miles per hour.

Be careful! You will go the wrong respond if you add the two speeds and carve up the answer past two.

How To Chronicle Speed To Distance And Time?

If y'all are traveling in a car that travels 80km along a route in 1 hour, nosotros say that y'all are traveling at an average of 80kn/h.

Average speed is the total distance divided by the total time for the trip. Therefore, speed is distance divided by time.

Instantaneous speed is the speed at which an object is traveling at whatsoever particular instant.

If the instantaneous speed of a machine remains the same over a period of time, so we say that the automobile is traveling with abiding speed.

The average speed of an object is the aforementioned as its instantaneous speed if that object is traveling at a abiding speed.
