4/7 of the children in the pool are girls
3/7 of the children in the pool are boys
4/7:3/7
4:3 is the ratio of girls to boys
13x(4+7)
=13x11
=143
So your answer is point 2.
Well there can be two different solutions for this but i will choose the easier one. Obviously one requires a system of equations which obviously will involve a lot of thinking and some good algebra solving in order for them to solve.
As for hit and trial it is very easy, we can just keep adding the distance as we know they are in different directions. 450 + 550 = 1000. So 1000 x 4 = 4000 miles. So after around 4 hours they will be 4000 miles apart if they continue at the same pace.
