Question

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. and traveled at an average rate of 496 mph. The second airplane left at 8:30 a.m. and traveled at an average rate of 558 mph. How many hours did it take the first plane to travel to the destination?
Let x represent the number of hours that the first plane traveled.
Enter an equation that can be used to solve this problem in the first box.
Solve for x and enter the number of hours in the second box.

Answer 1

First plane: 496x
Second plane:  558( x - 1/2) 

Equation: 496x = 558( x - 1/2) 

Solving  x = 9/2 ,  or  x = 4.5 hours.

Hope this helps.
