The first question...

A) it's cut of she travles 80.. 800. 800 km?

B) as for time it cannot be determined you do not know the speed


SEcond question is bird as you can us pythagorean theorem, 220-130 = 90

Thus x^2 = 400^2 + 400^2

x^2 = 320 000

x = 565.69 KM.



or if you want to get crazy..

Tan x = 400/400

Inverse tan = 45 degrees.

Sin 45 = 400/x

.707 = 400/x

x = 565.7 KM



*Edit* Oh.. what bearing... and who the hell is Rita...

Yeah lol, it was just a joke. 

Anyway, I got the answer right.

You need to find the height and width of the two triangles and subtract one from the other. Then you have 1 small triangle and then you can find the bearing.

It's impossible. Therefore you can't answer it. So it is hard.

There have been some very intesresting test I have taken.

The one test it askes you to read the entire test first.. the very last question says do not answer any questions to get perfect . 

You can't get the right answer there is no Rita

The correct answer is "indeterminate"; not enough information was given.  This is a valid (and correct) answer.
