## 解法 | ||
<pre> | ||
+-------------+---------+ | ||
| Column Name | Type | | ||
+-------------+---------+ | ||
| driver_id | int | | ||
| join_date | date | | ||
+-------------+---------+ | ||
driver_id is the primary key for this table. | ||
Each row of this table contains the driver's ID and the date they joined the Hopper company. | ||

### **Python3** | ||
<pre> | ||
+--------------+---------+ | ||
| Column Name | Type | | ||
+--------------+---------+ | ||
| ride_id | int | | ||
| user_id | int | | ||
| requested_at | date | | ||
+--------------+---------+ | ||
ride_id is the primary key for this table. | ||
Each row of this table contains the ID of a ride, the user's ID that requested it, and the day they requested it. | ||
There may be some ride requests in this table that were not accepted. | ||

<p>Table: <code>AcceptedRides</code></p> | ||
|
||
<pre> | ||
+---------------+---------+ | ||
| Column Name | Type | | ||
+---------------+---------+ | ||
| ride_id | int | | ||
| driver_id | int | | ||
| ride_distance | int | | ||
| ride_duration | int | | ||
+---------------+---------+ | ||
ride_id is the primary key for this table. | ||
Each row of this table contains some information about an accepted ride. | ||
It is guaranteed that each accepted ride exists in the Rides table. | ||
</pre> | ||
|
||
<p> </p> | ||
|
||
<p>Write an SQL query to compute the <code>average_ride_distance</code> and <code>average_ride_duration</code> of every 3-month window starting from <strong>January - March 2020</strong> to <strong>October - December 2020</strong>. Round <code>average_ride_distance</code> and <code>average_ride_duration</code> to the nearest <strong>two decimal places</strong>.</p> | ||
|
||
<p>The <code>average_ride_distance</code> is calculated by summing up the total <code>ride_distance</code> values from the three months and dividing it by <code>3</code>. The <code>average_ride_duration</code> is calculated in a similar way.</p> | ||
|
||
<p>Return the result table ordered by <code>month</code> in ascending order, where <code>month</code> is the starting month's number (January is <code>1</code>, February is <code>2</code>, etc.).</p> | ||
|
||
<p>The query result format is in the following example.</p> | ||
