The answer to the question is
36 mph on her way home and 45 mph on her way to visit her parents
Step-by-step explanation:
Total time for driving = 24 hours
Distance covered = 480 miles × 2
Speed of Jessie on her way home = x mph
Speed of Jessie on her way to visit her parents = x+9 mph
Therefore since speed = distance/time then we have
480/x + 480/(x+9) = 24
which gives
we cross multply and we have
24x²-744x-4320 = 0 which gives
(x+5)(x-36)×24 = 0 This means that her speed on her way home is either -5 mph (which is in reverse direction) or or 36 mph
Therefore her speed is 36 mph on her way home and 36+9 or 45 mph on her way to her parents
