Answer:
To get back to his home, Bryce must move 3 miles to the east.
Step-by-step explanation:
Let's solve this problem step by step, position by position:
Initially, Bryceis home(I am going to denote home as H).
H
Then, the problem states that Bryce rider 3 miles north, so:
N
3
H
3 is the distance, in miles. Bryce is at position N.
Then, he rides 3 miles west.
W 3 N
3
H
Now, Bryce is at position W. He goes 3 miles south, so:
W 3 N
3 3
S H
Bryce is now at S, and must get to H. So, he must move to the east. Each block has 3 miles, so he must move 3 miles.
To get back to his home, Bryce must move 3 miles to the east.
