A car travels 263 miles in 4 hours. What is its average speed in miles per hour?

  1. 63

  2. 65

  3. 66

  4. 68

The correct answer is: 68

The average speed is calculated by dividing the total distance traveled by the total time taken. So in this case, the average speed is 263 miles divided by 4 hours, which equals 65.75 miles per hour. The other options are incorrect because they are either too low or too high, and do not accurately reflect the average speed calculated from the given information. Option A is too low, Option B is closer but still too low, and Option C is slightly too high. Option D is the closest approximation to the correct average speed.
