d. 6 hours and 25 minutes

Explanation:

Step1: Identify the whole and decimal parts

The time is given as 6.75 hours. The whole number part (6) represents hours. The decimal part (0.75) needs to be converted to minutes.

Step2: Convert decimal hours to minutes

We know that 1 hour = 60 minutes. To convert 0.75 hours to minutes, we multiply 0.75 by 60: $0.75\times60 = 45$ minutes.

Step3: Combine hours and minutes

The whole number part is 6 hours, and the decimal part converts to 45 minutes. So the total time is 6 hours and 45 minutes.

Answer:

C. 6 hours and 45 minutes
