Question: Tony has to run several errands in a day. He needs to drive 10 miles to get groceries, 15 miles to get a haircut and 5 miles to go to a doctor's appointment. How many miles will Tony have driven when he is halfway through driving around for his errands?
Answer: First, we need to find the total number of miles Tony will be driving by adding 10 + 15 + 5 = 30 miles in total. To determine the halfway point, we simply divide the total number of miles by 2, performing 30 / 2 = 15 miles driven when Tony is halfway done. The answer is 15.
