Question
Hi please answer 1-3 please be organized, and please show work. Also, I attached the directions.
Transcribed Image Text:- (AV = 1) **assign variables** to values
- (BE = 2) **write the base equation** (Right now there is only one, but several more are coming soon.)
- (WE = 2) **create a working equation** from the base equation
- (S = 2) **substitute values** into the working equation
- (C = 2) **calculate an answer**
- (U = 1) **write the correct unit or unit symbol**

#### 1. Average Speed of a Skier
- **Problem:** What is the average speed of a skier who travels 1200 meters downhill in 60.0 seconds?
#### 2. Average Speed of a Car
- **Scenario:** In 5.0 hours, Darnley drives from Westboro to Felixburg, a distance of 325 kilometers. What is his average speed?
**Calculations:**
- **Given:**
- Time (\(\Delta t\)) = 5.0 hours
- Distance (\(\Delta d\)) = 325 km
- Speed (\(v\)) = ?
- **Formula:**
\[
v = \frac{\Delta d}{\Delta t}
\]
- **Substitute Values:**
\[
v = \frac{325 \text{ km}}{5.0 \text{ h}} = 65 \text{ km/h}
\]
#### 3. Average Speed of a Bullet
- **Problem:** A bullet travels 4.0 kilometers in 5.0 seconds. What is its average speed in meters per second?
These calculations demonstrate the basic principles of calculating average speed using distance and time, applicable to various contexts like skiing, driving, and bullet travel.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F212b1a89-0cf8-4ac8-b0ab-9e2a29138594%2F29746e15-d6f7-4760-ad28-064253929fd7%2F717q6cw_processed.png&w=3840&q=75)
