Write a function that models the following description: A man drove a total of 40 miles over a 2-hour period. (1 point)

Let's assume the function is named "calculate_speed".

The function will take two arguments: distance and time.

The input for distance will be 40 miles, and the input for time will be 2 hours.

So, the function definition will look like this:

```python
def calculate_speed(distance, time):
```

To calculate the speed, we'll use the formula speed = distance / time.

```python
def calculate_speed(distance, time):
speed = distance / time
return speed
```

Now, let's test the function with the given inputs:

```python
distance = 40
time = 2

result = calculate_speed(distance, time)
print("Speed:", result, "miles/hour")
```

Output:
Speed: 20.0 miles/hour

So, the function "calculate_speed" models the given description and returns the speed at which the man drove.

To write a function that models the given description, we need to determine the relationship between the distance traveled and the time taken. In this case, we know that the man drove a total of 40 miles over a 2-hour period.

Let's define the function "distance" (d) as a function of time (t), where d is in miles and t is in hours. We can write the function as:

d(t) = 40 / 2

Simplifying this expression:
d(t) = 20t

Thus, the function that models the given description is d(t) = 20t, where d represents the distance traveled in miles and t represents the time taken in hours.

To write a function that models the given description, we can define the relationship between the distance and time in terms of rate or speed. The formula to calculate speed is:

speed = distance / time

In this case, the man drove a total of 40 miles over a 2-hour period. So, the speed of the man's driving can be calculated as:

speed = 40 miles / 2 hours

Therefore, we can write the function in Python as:

```python
def calculate_speed(distance, time):
speed = distance / time
return speed
```

To use this function, you can simply call it with the given distance (40 miles) and time (2 hours) as arguments:

```python
distance = 40
time = 2
speed_result = calculate_speed(distance, time)
print(speed_result)
```

The output will be the speed in miles per hour.
