Answer 1

Rounded to the nearest tenth of a kilometer, Alex bikes approximately 26.1 kilometers each day that he bikes to work. So the correct answer is B: 26.1 km.

Explanation:

First, we can convert the total distance Alex bikes each week from miles to kilometers. Since 1 mile is approximately equal to 1.609 kilometers, 65 miles is approximately equal to 65 * 1.609 = 104.585 kilometers.

Since Alex bikes to work and back home four days a week, he bikes a total of 104.585 kilometers / 4 = 26.14625 kilometers each day that he bikes to work.

Rounded to the nearest tenth of a kilometer, Alex bikes approximately 26.1 kilometers each day that he bikes to work. So the correct answer is B: 26.1 km.
