Answer 2

Problem Analysis

The problem states that a coach traveled a ski track on a snowmobile at a speed of 2000 m per minute for 6 minutes. We need to determine the speed at which a skier traveled the same track if it took them 40 minutes to complete it.

Solution

To solve this problem, we can use the formula:

Speed = Distance / Time

Let's calculate the distance traveled by the coach first. The distance is given by:

Distance = Speed x Time

For the coach: - Speed = 2000 m/min - Time = 6 min

Substituting these values into the formula, we get:

Distance = 2000 m/min x 6 min = 12000 m

Now, let's calculate the speed of the skier. We know that the skier took 40 minutes to complete the same distance. Using the formula:

Speed = Distance / Time

For the skier: - Distance = 12000 m - Time = 40 min

Substituting these values into the formula, we get:

Speed = 12000 m / 40 min = 300 m/min

Therefore, the skier traveled the track at a speed of 300 m/min.

Answer

The skier traveled the track at a speed of 300 m/min.

Verification

Let's verify the answer using the given information.

The coach traveled the track at a speed of 2000 m/min for 6 minutes. The distance traveled by the coach is 12000 m.

The skier traveled the same track in 40 minutes. Let's calculate the distance traveled by the skier using the speed we calculated:

Distance = Speed x Time = 300 m/min x 40 min = 12000 m

The distance traveled by the skier matches the distance traveled by the coach, which confirms that our answer is correct.

Conclusion

The skier traveled the track at a speed of 300 m/min.
