An airplane flew at an average rate of 600 miles per hour from tokyo to seattle. because of a strong headwind, the average rate of the return trip was only 480 mph. the round trip took 18 hours. which equation can be used to determine the time for each leg?

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  

-2x + 7 = 7

subtract 7 from both sides.

-2x = 0

divide both sides by -2.

x = 0
