Answer:
5√3 miles per hour
Step-by-step explanation:
Throughout their journey, the component of velocity of rowboat B to the east is the same as that of rowboat A:
(10 mph)(cos(π/3)) = 5 mph
Meanwhile, the component of velocity of rowboat B to the north is ...
(10 mph)(sin(π/3)) = 5√3 mph
Since rowboat A is always traveling in a direction that is at right angles to the direction between the boats, it contributes nothing to their relative speed. Since rowboat B is always directly north of rowboat A, its speed to the north is their relative speed.
The distance between the rowboats is increasing at 5√3 mph ≈ 8.66 mph.

1) y=-5x
It would be this one because even if you dilate it, it would remain unchanged because it passes through the origin (0, 0) and wouldn't change the equation. The rest have y intercepts and that would cause the equation to change.
Hope this helps :)

Step-by-step explanation:
I would say yardstick becuase it just makes more sense. Its biggger and larger and you will get a better measurement.
