Answer 1

Problem Analysis

We are given that Lukas traveled a part of the road on a bicycle and the remaining distance on foot. It took him four times longer to walk the remaining distance than it did to ride the bicycle. The total time Lukas spent on the journey was 20 hours. We need to determine the fraction of time Lukas spent riding the bicycle and walking, as well as the number of hours he spent on each mode of transportation.

Solution

Let's assume that Lukas spent x hours riding the bicycle. Since it took him four times longer to walk the remaining distance, he spent 4x hours walking. The total time Lukas spent on the journey is given as 20 hours.

To find the fraction of time Lukas spent riding the bicycle, we can use the equation:

x + 4x = 20

Simplifying the equation, we have:

5x = 20

Solving for x, we get:

x = 4

Therefore, Lukas spent 4 hours riding the bicycle and 4 * 4 = 16 hours walking.

Answer

Lukas spent 4 hours riding the bicycle and 16 hours walking.
