Answer:
(7, 385) is the new point, and it represents 385 miles in 7 hours
Explanation:
Given that the initial point is (1, 55)
Since the x coordinates changes to 7, we need to make similar change to the y-coordinate.
1 becomes 7, when it is multiplied by 7
So, multiplying 7 by 55, we have 385.
Therefore, the new point is (7, 385)
This represents 385 miles in 7 hours
