Confirmation on 2 problems

1. How many 2-digit numbers are divisible by 4? Is it 22?
2.Joe began to increase the speed of his car at 2 pm. Since that time, the speed of Joe's car has been increasing by 1.5 miles per hour for each half minute that has passed. If his car is now travelling at 65.5 mph, for how many minutes has the car been exceeding the 55mph speed limit? He starts at 0mph.
3. Ang has x dollars and Julia has y dollars. Ang gives Julia 1/3 of his money. Julia spends 1/4 of the total money she now has. Express the money spent in x and y.
Is it y/4 + x/12
4. A cube has 1000 cubic feet of volume. The container is being filled with 7 cubic feet of water per minute. It is draining at 2 cubic feet per minute. If it is half full at 9 am, at what time is it full? Is it 10:40 am?

Re: Confirmation on 2 problems

Hi;



In mathematics, you don't understand things. You just get used to them.
If it ain't broke, fix it until it is.
Always satisfy the Prime Directive of getting the right answer above all else.
