Answer:
6.5 miles per hour
Step-by-step explanation:
At first, Jim was paddling against the current for 3 hours. Then, he paddled for 1 hour with the help of the current.
Let x be Jim's rate without the current and y be the rate of the current:
By solving the linear system, we can find the rate of the current y:
The current has a rate of 6.5 miles per hour.
Correct Answer:
Second option
Solution:
The given sequence is:
2.2, 6.6, 11, ...
If we observe the sequence it is an Arithmetic Sequence as the difference between two consecutive terms is the same.
6.6 - 2.2 = 4.4
11 - 6.6 = 4.4
First we find the general term for this sequence.
first term = 2.2
d = 4.4
So,
This general term will be placed inside the summation sign with limits from 1 to 5 to give the sum of first 5 terms of the given sequence. So the correct answer is Second Option
