To calculate: Thedistance travelled by her if she reached the finished line in 15 seconds.
Answer to Problem 56E
The distance travelled by her is
Explanation of Solution
Given information:
The distance travelled in first second is 5 feet and for each subsequent second the distance increased by 7 feet.
Formula used:
A sequence with first term as
The sum of n terms of the arithmetic sequence is
Calculation:
Consider the provided information that distance travelled in first second is 5 feet and for each subsequent second the distance increased by 7 feet.
The above situation forms an arithmetic sequence as a constant increase in distance is there for each subsequent second.
Denote the distance travelled by her if she reached the finished line in 15 secondsby
Recall that a sequence with first term as
The sum of n terms of the arithmetic sequence is
Here
Again apply the sum of n terms of the arithmetic sequence
Thus, the distance travelled by her if she reached the finished line in 15 secondsis
