You can put this solution on YOUR website!
The time for each plane is the same, 2.5 hours.
The sum of distance each plane traveled equals 2300 miles.
Format
Plane --------------rate----------time---------distance
Fast plane__________r+100_________2.5__________(r+100)2.5
Slow plane__________r ____________2.5___________ r2.5

Sum of distances, 2300=%28r%2B100%29%2A2.5%2Br%2A2.5
Solve for r, the slower plane and then add 100 to find rate of faster plane.
