Answer:
To solve this problem, we will use the following steps:
Step 1: Convert the minutes to hours by dividing the minutes by 60: 45 minutes / 60 = 0.75 hours
Step 2: Add the hours and minutes together to find the total time: 3 hours + 0.75 hours = 3.75 hours
Step 3: Multiply the total time by the average speed to find the distance: 3.75 hours * 80 km/hour = 300 km
Final Answer: Tim drives 300 km.
