Answer:
121 days; 30 full days
Step-by-step explanation:
to find how much days she takes you divide 2175 by 18
2175 / 18 is 120.833333
it will take her at least 121 days because you need to round up
the last portion of the hike would be a quarter of the hike
you would divide the final time by 4 and that is your answer
121 / 4 is 30.25
you have to round down because .25 is not a full day
she hiked 30 full days
