Lisa is flying from Bush Intercontinental Airport in Houston, TX to Newark International Airport in New
Jersey with the wind. The trip is approximately 1415 miles. Lisa then flies from Newark International
Airport to Dallas-Fort Worth International Airport against the wind which is approximately 1372 miles
away. The wind speed is the same on both parts of her trip. Without the effect of wind, her airplane
travels at an average rate of 530 miles per hour for both trips. The total time Lisa spends in the air is
8.5 hours. What is the speed of the wind?
