b) 10,690,000 feet

c) 10,690 feet

A line of one million cars would be about _______ miles long. (Round to the nearest mile)

a) 1 mile

b) 2 miles

c) 20 miles

d) 2,020 miles

Answer 1

The length of a line of one million cars assuming an average car length of 15 feet would be approximately 10,690,000 feet or 2,840 miles. The closest option to the calculated length in feet is (b) 10,690,000 feet.

Step-by-step explanation:

To estimate the length of a line of one million cars, we need to make an assumption about the average length of a car. A common average length is around 15 feet per car. Therefore, a line of one million cars would be 1,000,000 cars × 15 feet/car = 15,000,000 feet long.

Now, to convert feet to miles, we use the fact that there are 5,280 feet in one mile. So, a line of 15,000,000 feet divided by feet per mile gives us:
15,000,000 feet ÷ 5,280 feet/mile ≈ 2,840 miles. Rounding to the nearest mile, we get approximately 2,840 miles long.

Therefore, the correct answers are:
