Answer 1

put one rate at r, the other at r+50 and solve
\[r + r+50 = 550\]

Answer 2

i did then i divided by 50

Answer 3

i see

Answer 4

i did but i have no idea what to do with the 1/2 hr and planes being 275 miles apart

Answer 5

i thought since you had miles per hour better to work with one hour instead of half an hour. that is why i doubled it

Answer 6

\]2r+50=550\]
\[2r=500\]
\[r=250\] and
\[r+50=300\]
