Need help finding the average speed.
Snowcat [4.5K]

Explanation:

To find the average of these numbers, we just have to add the three numbers together and divide by 3.

  • 2.07 + 0. 74 + 1.33 = 4.14. 4.14 / 3 = 1.38
  • 1.09 + 1.40 + 0.31 = 2.8. 2.8 / 3 ≈ 9.3333333/ 9 1/3
  • 0.95 + 1.61 + 0.56 = 3.12 / 3 = 1.04
  • 0.81 + 1.89 + 1.08 = 3.78 / 3 = 1.26
