Answer 1

1) 480÷240=2ч
2) 480÷160=3ч
3) 240-120=120м
да,догонит

Answer 3

Problem Analysis

We are given that Valya ran from school to a park that is 480 km away. Katya ran after Valya and when Valya was 120 m away from her, we need to determine if Katya will catch up to Valya. We are also given that Katya runs at a speed of 240 m/min and Valya runs at a speed of 160 m/min.

Solution

To determine if Katya will catch up to Valya, we need to compare the distances they cover over time.

Let's calculate the time it takes for Valya to reach the park:

Distance = Speed × Time

480 km = 160 m/min × Time

Time = 480 km / 160 m/min

Time = 3 hours

So, it takes Valya 3 hours to reach the park.

Now, let's calculate the distance Katya covers in 3 hours:

Distance = Speed × Time

Distance = 240 m/min × 3 hours

Distance = 720 m

Since Katya covers a distance of 720 m in 3 hours, and Valya is initially 120 m away from her, we can subtract the initial distance from the distance Katya covers:

720 m - 120 m = 600 m

Therefore, Katya will catch up to Valya when the distance between them is 600 m.

Conclusion: Katya will catch up to Valya when the distance between them is 600 meters.
