Final answer:
The construction crew built a total length of 27.5 kilometers of road by working for 10 days, building 2 3/4 kilometers each day.
Step-by-step explanation:
To find the total length of road built, we need to multiply the length of road built each day by the number of days the crew worked. In this case, the crew built 2 3/4 kilometers of road each day, and they worked for 10 days.
To calculate the total length, we can use multiplication. 2 3/4 can be written as an improper fraction as 11/4. So, the total length of road built is 11/4 * 10 = 110/4 = 27.5 kilometers
Therefore, the construction crew built a total length of 27.5 kilometers of road.
