Answer 2

Problem Analysis

We are given that a helicopter flew 440 km in 2 years, while a plane was on the road for 3 years. The speed of the plane is 3 times greater than the speed of the helicopter. We need to determine how many more kilometers the plane traveled compared to the helicopter.

Solution

To solve this problem, we need to find the distance traveled by the plane and the helicopter.

Let's assume the speed of the helicopter is x km/year. Since the helicopter flew 440 km in 2 years, we can set up the equation:

Distance traveled by the helicopter = Speed of the helicopter * Time taken by the helicopter

440 km = x km/year * 2 years

Simplifying the equation, we find:

x = 440 km / 2 years x = 220 km/year

Now, let's find the distance traveled by the plane. We are given that the speed of the plane is 3 times greater than the speed of the helicopter. Therefore, the speed of the plane is 3x km/year.

Since the plane was on the road for 3 years, we can set up the equation:

Distance traveled by the plane = Speed of the plane * Time taken by the plane

Distance traveled by the plane = 3x km/year * 3 years Distance traveled by the plane = 9x km

To find how many more kilometers the plane traveled compared to the helicopter, we subtract the distance traveled by the helicopter from the distance traveled by the plane:

Difference in distance = Distance traveled by the plane - Distance traveled by the helicopter

Difference in distance = 9x km - 440 km

Now, let's substitute the value of x that we found earlier:

Difference in distance = 9 * 220 km/year - 440 km

Calculating the difference in distance:

Difference in distance
