Two planes left the same airport traveling in opposite directions. The first plane left at 9:00 a.m. and 2.25 h later, the two planes were 1825 mi apart. The second plane left at 10:00 a.m. and its average rate was 108 mph slower than the first plane's average rate. What was the first plane's average rate?
Let x represent the first plane's average rate.
