Answer:

  A.  0.5< t < 0.75

Step-by-step explanation:

We can use the relation ...

  time = distance / speed

to find the number of hours it took Johanna to walk around the lake.

  time = (2 mi)/(3 mi/h) = 2/3 h

2/3 is between 1/2 and 3/4, so the first answer choice describes the interval containing Johanna's time:

  0.5 < t < 0.75

Marianna [84]
Set it up like a regular equation. I used:
3x+135 \ \textless \  6x

As you can see, however, I inserted the "less than" symbol rather than the equal sign because values greater than a certain value can also equal "x". Solve it like a normal equation and you will arrive at:
<u>
</u>x \ \textgreater \  45

This means that, as long as x is greater than 45, "6x" will be greater than "3x+135". Thus, if you bring 46 students, the Science Center will cost less.
