How many kilometers is it from Barber Park to Eagle Island? Answer by fractalier(6550) (Show Source):
You can put this solution on YOUR website! Remember D = RT, distance = rate*time.
Let the time for the initial trip be t.
The return trip time is t - 4.
The distances are equal so
6t = 18(t - 4)
6t = 18t - 72
-12t = -72
t = 6 hours
Thus the distance is 6t or 36 km.
