Multiple choice

A chopper travels from Vegas to California, covering a distance of 600 km in 300/(x + 1) hours. What is the average speed of the chopper?

  1. 2(x + 1)

  2. 1/2(x + 1)

  3. 900/(x + 1)

  4. 1/(x + 1)

  5. e

A Correct answer
Explanation

Average speed = Total distance / Total time. Distance = 600 km. Time = 300 / (x + 1). Average speed = 600 / (300 / (x + 1)) = 600 * (x + 1) / 300 = 2(x + 1).

AI explanation

Using the formula for average speed, which is total distance divided by total time, we divide the distance of 600 km by the time of 300 divided by (x + 1) hours. This gives 600 multiplied by (x + 1) divided by 300. Simplifying this yields an average speed of 2(x + 1) km/hr.
