How Common Is It For A Nine Year Old (3rd Grader) To Have Problems With “phonetics”?

My son is what I would consider an “average” reader but maybe his reading ability is average for his age? He can read books like “Magic Tree House” but not something like the “Harry Potter Series”. Is this typical? I’m considering having the school intervene but am not sure if I am expecting too much.

Problems With Disney World Tickets At The Gate?

We are going to Disney from December 8th to the 11th. We are not staying on the property (just off of it, in a house).
We will go to Magic Kingdom, Universal Studios (right name?) and Sea World. We have 7 adults and 3 children.
It seems to us that multi-day passes and/or park-hopper passes will not help us. Is that right?
Big issue: should we buy tickets before we arrive. If we do, we will have to decide on which days we will go to each park (right?). If we do not, we will have to buy them at the gate, and this might lead to long waits. Do you think the waits would be long given our dates there?

Two Story Problems From Intermediate Algebra.?

I went through some Algebra II story problems from my textbook. I am a little stuck though on two problems from this section. The problems read:
Problem #1:
A train leaves union station for central station, 216 km away at 9 am. One hour later a train leaves central station for union station. they meet at noon. If the second train had started at 9 am and the first train at 10:30 am they would still have met at noon. Find the speed of each train.
Problem #2:
A magic shows audience of 100 people consists of adults, students, and children. The ticket price for adults is $10, students $3 and children 50 cents. The total amount of money taken in is $100. How many adults, students, and children are in attendance? Does there seem to be some information missing? Do some more careful reasoning.
