Answer:
Trip 1: 15
Trip 2: 14
Explanation:
Divide to find the number of cars the ferry can take per trip.
29 / 2 = 14.5
Heres the issue right, we can't cut a car in half to make the trips even. The ferry will need to either carry one extra car for one trip or leave one behind both trips but the question states, "in two groups".
Best of Luck!
