Answer 2

Comparison of Speed between Boat and Ship

To compare the speeds of the boat and the ship, we can calculate their respective speeds using the given distances and times.

Speed of the Boat (Kater): - Distance traveled by the boat: 0.4 kilometers - Time taken by the boat: 20 seconds

To calculate the speed of the boat, we can use the formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

Using this formula, the speed of the boat can be calculated as: \[ \text{Speed of the boat} = \frac{0.4 \, \text{km}}{20 \, \text{s}} \]

Speed of the Ship (Teplohіd): - Distance traveled by the ship: 12000 meters (which is equal to 12 kilometers) - Time taken by the ship: 20 minutes (which is equal to 1200 seconds)

To calculate the speed of the ship, we can use the same formula: \[ \text{Speed} = \frac{\text{Distance}}{\text{Time}} \]

Using this formula, the speed of the ship can be calculated as: \[ \text{Speed of the ship} = \frac{12 \, \text{km}}{1200 \, \text{s}} \]

Calculating the Speeds

Let's calculate the speeds of the boat and the ship using the given distances and times.

Speed of the Boat (Kater): \[ \text{Speed of the boat} = \frac{0.4 \, \text{km}}{20 \, \text{s}} = 0.02 \, \text{km/s} \]

Speed of the Ship (Teplohіd): \[ \text{Speed of the ship} = \frac{12 \, \text{km}}{1200 \, \text{s}} = 0.01 \, \text{km/s} \]

Comparison of Speeds

From the calculations, we can see that the boat (Kater) has a speed of 0.02 km/s, while the ship (Teplohіd) has a speed of 0.01 km/s.

Therefore, the boat (Kater) is moving faster than the ship (Teplohіd).
