Answer:
I use faction
Step-by-step explanation:
The first boat.
÷ 10 =
÷ 2 =
The first boat move
The second one do the same
÷ 10 =
÷ 2 =
That is the speed of each boat.
The first boat need 50 minutes to get to the other side
2000 ÷ 2 =1000
1000 x 3 = 3000
3000 ÷ 60 = 50
The second boat need 66.6666666667 minutes to get to the other side
200 ÷1.5 = 1333.33333333
1333.33333333 x 3 = 4000
4000 ÷ 60 = 66.6666666667
