Answer:
(2,0)
Step-by-step explanation:
The current coordinate of M are (4,0). This means the side length of OM is 4. To scale down by a factor of 1/2, the side length would become 4*1/2 = 2.
This side is now 2 and would place the point M at (2,0).
Let
x = time of Byran's work
x + 10 = time of Andy's work
Rate is usually expressed a reciprocal. The total rate will be 12 minutes.
1/x + 1/(x + 10) = 1/12
The value of x will be 20 minutes.
Therefore Byran can take 20 minutes while Andy can take 30 minutes.
