Question

An object's motion over time:

1. Moves at a speed of 37 km for two hours.
2. Speeds up gradually over 15 minutes until it reaches a constant speed of (37+10) km/h, which it travels for another 45 minutes.
3. Travels a distance of 50km over the next 3/7 hours.
4. Comes to a stop for 1 hour.

Answer 1

The object's motion can be divided into four stages: 1. Moves at a speed of 37 km/h for two hours. 2. Speeds up gradually over 15 minutes until it reaches a constant speed of 47 km/h, which it travels for another 45 minutes. 3. Travels a distance of 50 km over the next 3/7 hours. 4. Comes to a stop for 1 hour.

Step-by-step explanation:

The motion of the object can be divided into four stages:

1. The object moves at a speed of 37 km/h for two hours.
2. The object gradually speeds up over 15 minutes until it reaches a constant speed of 47 km/h, which it travels for another 45 minutes.
3. The object travels a distance of 50 km over the next 3/7 hours.
4. The object comes to a stop for 1 hour.

Each stage represents a different type of motion and duration. The object's motion over time can be described using these stages.
