A) what do you mean 'half house'?

B) If they are both traveling 60 miles at a constant rate then you need to find miles/hour (miles per hour) so:

Line: M/H - 60/65 = .9

Diego: M/H 60/70 = .85

Line had the bigger number which means that he went faster.

I don’t understand this problem
ikadub [295]

Hello! the answer is c

First of all let's eliminate the answers that do not make sense. For A. numbers are NOT irrational because they are a fraction. Numbers are also not irrational because they are a repeating number. C and D are both correct as fractions and terminating decimals are both rational numbers.

34/3≈11.33333333

By using a certain formula you can convert repeating decimals to a fraction. But most people know that .3333333 is 1/3. This gives us 11 1/3 as our answer. So what does it match? It is not a terminating decimal. It repeats but can be written as a fraction. Therefore our answer is C) Rational, because it is a fraction.

I hope this helps!
