This is the picture of my(and my partner's) "Pennsylvania Turnpike Investigation." I'm going to explain what we did to get the answers. I think the number lines are wrong so I'm just going to make new ones to make it more easier to understand.

1) How many gallons of gas and what fraction of a full tank of gas did Maria use on the turnpike driving from her house to Lance's house?

- First, we found out that Maria's to Lance's house was 110 miles.
-
110 miles is also 3 and 1/3. 3 and 1/3 is how much gallons of gas, out of 15, she used to get to Lance's house.

2) What fraction of a full tank of gas did she use on the turnpike driving to the combined distance from her house to Lance's house to Alicia's house?

- We already knew the distance from Maria's to Lance's so we had to figure out the distance to Lance's to Alicia's.
- To get that, we subtracted 242 by 55 and we got 187.
-
So we added them together to get 297 miles.
- Then, we did 297 divided by 33 (which is the miles by the miles per gallon) and we got 9.
- She used 9 gallons out of 15 gallons to get to the combined distances.

3)How much time will she spend driving on the turnpike when she drives back home to Philadelphia?

- First, we turned 110 miles into time which was 1 hour and 50 mins.
- Then, we subtracted 10 minutes to get 1 hour and 40 mins because we couldn't find another way to get 1 hour and 40 mins.
- We did the same thing to 187 miles and we got 3 hours and 7 mins then we subtracted 10 mins and we got 2 hours and 57 mins.
- We added it together and we got 4 hours and 37 minutes
