Answer
The average speed of the plane is 600 mph.
Solution
1. The average speed \( s \) is given by the formula
\[
s = \frac{d}{t}
\]
where \( d \) is the distance and \( t \) is the time.
2. Here, the distance is \( 1950 \) miles and the time is \( 3.25 \) hours. Substitute the values into the formula:
\[
s = \frac{1950}{3.25}
\]
3. Performing the division:
\[
s = 600 \text{ mph}
\]
Thus, the average speed of the plane is \( 600 \) mph.

Simplify this solution Bonus Knowledge
To find the average speed, you can use the formula: speed = distance / time. Here, the distance from Chicago to San Francisco is 1,950 miles, and the time taken is 3.25 hours. Plugging these values into the formula gives you: Average speed = 1,950 miles / 3.25 hours = 600 mph. So, the average speed of the airplane was 600 miles per hour! For those who love a good visual, drawing a simple graph could actually help illustrate the relationship between speed, distance, and time with different examples. This way, you can see how maneuvering those numbers can lead to a variety of scenarios and speeds! Keep experimenting!
