Two airplanes left the same airport and arrived at the same destination at the same time. The first airplane left at 8:00 a.m. a
nd traveled at an average rate of 496 miles per hour. The second airplane left at 8:30 a.m. and traveled at an average rate of 558 miles per hour. Let x represent the number of hours that the first plane traveled. Write an equation that can be used to solve the value of x.
