The sum of first 46 positive and odd numbers is 2116
<em><u>Solution:</u></em>
Given that we have to find the sum of first 46 positive and odd numbers
<em><u>The sum of first "n" natural odd numbers which are positive is given as:</u></em>

Here, n = 46
Therefore,
sum of first 46 positive and odd numbers = 
sum of first 46 positive and odd numbers = 
Thus the sum of first 46 positive and odd numbers is 2116

Answer:
The answer to your question is 166 mi/h
Step-by-step explanation:
Data
ve = rate eastbound train
vw = rate westbound train = ve - 14
distance = d = 900 mi
time = t = 5 h
Formula
v = 
Substitution and simplification

Now, substitute this value in the equation of vw
vw = 180 - 14
Result
vw = 166 mi/h
