Laura paddles in her canoe at a speed of 5 mph for 5 miles.
As we know that

Substitute the values we get

Laura hops on her windsurfer and sails for 12 miles at a speed of 6 mph.
Again using the above formula we can write

Hence from equation (i) and (ii), we can say total time of travel
Three pieces are left. Hope this helps!

ANSWER
The coordinates of the image are (2,2)
EXPLANATION
The mapping for a reflection across the line y=k is :

We want to find the image of the point (2,-4) after a reflection in the line y=-1.
In this case k=-1.

This simplifies to,


Hence the image is (2,2)
The answer would be a. 288. hope that helped
