Question

Challenge! Ready? A boat in calm seas travels in a straight line and ends the trip 22 km west and 53 km north of its original position. To the nearest tenth of a degree, find the direction of the trip.

Answer 1

You use that right?

Answer 2

So is it just the normal challenge or are you actually solving it this time?

Answer 3

I wasn't sure about this one.

Answer 4

Assume the start is at (0,0)
The end is at (-22,53).
----


direction = tan^-1(-53/22) = -67.46
But the angle is in the 2nd Quadrant.
So, direction = -67.46 + 180 = 112.54 degrees. Is this right?
