Question 1149021: A family vacation trip took 12 hours. Of the total distance, 4/5 was in a car and 1/5 was in a boat, and the car traveled 5 times as fast as the boat. How much more time, in hours, was spent in the boat than in the car? Answer by ikleyn(52887) (Show Source):
Let x be the rate of the boat; then the rate of the car is 5x.
And let "d" be the traveled distance.
The time spent on the car was = hours.
The time spent on the boat was = .
The ratio = : = .
Thus we need to separate 12 hours in two parts in proportion .
So, the parts are = = hours for the car and 12 - = hours for the boat.
