The person was speeding at 93 miles per hour.

Step-by-step explanation:

  • Step 1: Given the equation to find speeding fine F = 7(s - 65) + 70
  • Step 2: Substitute given details in the equation and find s. F = $266

⇒ 266 = 7(s - 65) + 70

⇒ 266 = 7s - 455 + 70

⇒ 266 = 7s - 385

⇒ 651 = 7s

⇒ s = 651/7 = 93
