Answer 2

Problem Analysis

We are given that a seagull flew 180 km in 4 hours and during this time, it covered 2/3 of the distance from an island to the Earth. We need to determine the distance from the Earth to the island and the speed at which the seagull was flying.

Solution

Let's break down the problem step by step.

1. Distance covered by the seagull: The seagull flew 180 km in 4 hours. Therefore, its average speed can be calculated as 180 km / 4 hours = 45 km/h.

2. Distance from the Earth to the island: During the 4 hours of flight, the seagull covered 2/3 of the total distance from the island to the Earth. Let's assume the total distance from the island to the Earth is represented by d. Therefore, the distance covered by the seagull can be calculated as (2/3) * d.

3. Using the average speed formula, we can calculate the time taken by the seagull to cover the distance from the island to the Earth: time = distance / speed. Substituting the values, we get (2/3) * d / 45 = 4 hours.

4. Solving the equation for d, we can find the distance from the Earth to the island.

Let's calculate the distance from the Earth to the island and the speed of the seagull.

Calculation

Let's solve the equation (2/3) * d / 45 = 4 to find the distance from the Earth to the island.

(2/3) * d / 45 = 4

Multiplying both sides by 45:

(2/3) * d = 4 * 45

Simplifying:

(2/3) * d = 180

Multiplying both sides by 3/2:

d = (180 * 3/2) = 270 km

Therefore, the distance from the Earth to the island is 270 km.

Now, let's calculate the speed of the seagull.

The speed of the seagull is given as 45 km/h.

Therefore, the seagull was flying at a speed of 45 km/h.

Answer

The distance from the Earth to the island is 270 km and the seagull was flying at a speed of 45 km/h.
