Answer 2

Problem Analysis

To solve this problem, we need to find the speed at which Peter walked to the lake. We are given that Peter walked from the village to the lake in 0.7 hours (h) and returned in 0.8 h. The total distance covered by Peter is 6.44 kilometers (km). We need to calculate the speed at which Peter walked to the lake.

Solution

To find the speed, we can use the formula:

Speed = Distance / Time

Let's calculate the speed at which Peter walked to the lake.

Calculation

The distance covered by Peter is 6.44 km. The time taken to walk from the village to the lake is 0.7 h.

Speed = 6.44 km / 0.7 h

Using a calculator, we can find that the speed at which Peter walked to the lake is approximately 9.2 km/h.

Answer

Peter walked to the lake at a speed of approximately 9.2 km/h.
