 Question 38369: Kara floats from Barber Park to Eagle Island at 6 km/h. She returns by motorboat at 18 km/h. The float trip takes 4 hours longer than the motorboat trip. How many kilometers is it from Barber Park to Eagle Island?Answer by fractalier(2101)   (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.
