Problem Analysis

We are given that Vitya is trying to catch up to Tanya. The distance between them is 1.56 km. Vitya is running at a speed of 8.5 km/h, while Tanya is walking at a speed of 3.3 km/h. We need to determine how much time it will take for Vitya to catch up to Tanya.

Solution

To solve this problem, we can use the formula: time = distance / speed. We'll calculate the time it takes for Vitya to cover the distance between them.

Let's calculate the time it takes for Vitya to cover the distance of 1.56 km at a speed of 8.5 km/h:

Time taken by Vitya = Distance / Speed = 1.56 km / 8.5 km/h

Calculating this, we get:

Time taken by Vitya = 0.18352941176 hours

To convert this time to minutes, we multiply by 60:

Time taken by Vitya = 0.18352941176 hours * 60 minutes/hour

Calculating this, we get:

Time taken by Vitya = 11.0117647056 minutes

Therefore, it will take Vitya approximately 11.01 minutes to catch up to Tanya.

Answer

Vitya will catch up to Tanya in approximately 11.01 minutes.
