It will take them about 26 days to complete the expedition
<h2>Proportion and distance</h2>According to the information, the team of explorers is to travel 19.12km in 12 hours
If they are expected to travel 1014.15km in total, the total time taken is given as:
1014.15km = x
Take their proportions:
Convert the time taken to days;
This shows that it will take them about 26 days to complete the expidition.

Suppose
At the same time, we can write
Note that (just reverse the sum). Let's pair the first terms of
and
, and the second, and the third, and so on:
Now, each grouped term in the sum on the right side adds to 151. There are 52 grouped terms on that same side (because there are 50 numbers in the range of integers 51-100, plus 50 and 101), which menas
But , as we pointed out, so
Answer:
<em /><em />
Step-by-step explanation:
STEP 1: <em>Rewrite so n is on the left side of the inequality.</em>
STEP 2: <em>Subtract 2 n from 6 n .</em>
STEP 3: <em>Move all terms containing n to the left side of the inequality.</em>
