Problem Analysis

We have a group of tourists consisting of 45 Chinese, 35 Germans, and 25 Americans who want to cross the English Channel (La Manche) together in boats. Each boat can only accommodate 7 people. We need to determine the minimum number of boats required to transport all the tourists simultaneously.

Solution

To find the minimum number of boats required, we need to divide the total number of tourists by the maximum number of tourists that can fit in one boat.

Let's calculate the total number of tourists: - Chinese tourists: 45 - German tourists: 35 - American tourists: 25

Total number of tourists = 45 + 35 + 25 = 105

Now, let's calculate the minimum number of boats required: - Maximum number of tourists per boat = 7

Minimum number of boats required = Total number of tourists / Maximum number of tourists per boat

Minimum number of boats required = 105 / 7 = 15

Therefore, the minimum number of boats required to transport all the tourists simultaneously is 15.

Answer

The minimum number of boats required to transport all the tourists simultaneously is 15 (Option C).
