Answer:

  • 6 mph

Step-by-step explanation:

Refer to attached table for inputs

Below equation is for total time traveled (middle column of table). Solving for x:

  • 20/(14 + x) + 20/(14 - x) = 3.5
  • 20(14 - x) + 20(14 + x) = 3.5(14 + x)(14 - x)
  • 20*2*14 = 3.5(14² - x²)
  • 160 = 196 - x²
  • x² = 36
  • x = √36
  • x = 6

Speed of wind is 6 miles per hour
