1100-(2*200)=700
700/2=350
350/2=175
175+200=375
375 mph and 175 mph
Work check:
375+175= 550
550*2=1100
you first have to subtract 200 mi for each hour because of speed difference
then, divide by two for the mph of both planes. then divide be 2 for the slower plane's speed and add 200 to the slow plane's speed for the faster's speed. the bottom adds the two speeds then adds the two hour factor in to show they would be 1100 mi apart.
