Problem Analysis

In this problem, Galileo arrived at the sports center at 10:00 AM and participated in four activities: tennis, swimming, cycling, and resting at the cafe. He spent half an hour less on each subsequent activity compared to the previous one. We need to determine how much time Galileo spent playing tennis.

Solution

Let's assume that Galileo spent x hours playing tennis. According to the problem, he spent half an hour less on each subsequent activity. Therefore, he spent (x - 0.5) hours swimming, (x - 1) hours cycling, and (x - 1.5) hours resting at the cafe.

To find the total time Galileo spent on these activities, we can add up the time spent on each activity:

x + (x - 0.5) + (x - 1) + (x - 1.5) = 6

Simplifying the equation, we get:

4x - 4 = 6

Adding 4 to both sides of the equation, we have:

4x = 10

Dividing both sides of the equation by 4, we find:

x = 2.5

Therefore, Galileo spent 2.5 hours playing tennis.

Answer

Galileo spent 2.5 hours playing tennis.
