Answer:
Step-by-step explanation:
Speed on going = 600 miles per hour
Let t be the time om going
So, Distance =
Distance =
Speed on return = 480 miles per hour
The round trip took 18 hours.
So, Time on returning = 18-t
Distance =
Distance =
Distance will remain same on going and returning
So,
Hence equation can be used to determine the time for each leg is
