Calculating the Total Road Repaired in Three Weeks

To calculate the total road repaired in three weeks, we can use the information provided about the lengths of road repaired in each week.

Given: - First week: 18.8 km - Second week: 6.4 km more than the first week - Third week: 2.9 km more than the first week

Let's calculate the total road repaired in three weeks step by step.

Step 1: Calculate the length of road repaired in the second week. - Length repaired in the second week = 18.8 km + 6.4 km - Length repaired in the second week = 25.2 km

Step 2: Calculate the length of road repaired in the third week. - Length repaired in the third week = 18.8 km + 2.9 km - Length repaired in the third week = 21.7 km

Step 3: Calculate the total length of road repaired in three weeks. - Total length repaired = Length repaired in the first week + Length repaired in the second week + Length repaired in the third week - Total length repaired = 18.8 km + 25.2 km + 21.7 km - Total length repaired = 65.7 km

So, 65.7 kilometers of road were repaired in three weeks.
