Answer:
Therefore Jenna ran 20 kilometers in a week.
Step-by-step explanation:
<u><em>Jenna ran 2 7/8 kilometers each day for a week. How far did she run in all?</em></u>
<u><em /></u>
We can simply use proportion to solve this;
But we need to know that 7 days = 1 week
If Jenna ran 2 kilometers each day, we are now going to find how many kilometers she run in a week(7 days)
Let x be the total distance she ran in a week
2 kilometers = 1 day
x = 7 day
Cross-multiply
x = 2 × 7
= × 7
=
=20 kilometers
Therefore Jenna ran 20 kilometers in a week.
