speed of private jet --- x mph
speed of commercial jet --- 2x-143 mph
They both went the same distance, so ...
4(2x - 143) = 6x
solve for x
a private jet flies the same distance in 6 hours that a commercial jet flies in 4 hours.if the speed of the commercial jet was 143 mph less than 2 times the speed of the private jet, find the speed of each jet
