Pythagorean Theorem Problem- Two planes take off at the same time from the same airport. One flies due south at 180 km/hr and the other flies due east at 240 km/hr. How far apart are they at the end of 45 minutes? Thanks!

Question

first figure out how far they went
then draw the triangle

I think the biggest issue I'm having with Pythagorean Theorem is picturing the triangle. After I see the picture I know exactly what to do. I know for sure 252 and 39 miles are two different sides of the triangle. But which sides?

anonymous · Answer

i don't get either of those numbers 
how did you get them?

anonymous · Answer

Sorry i meant 45 and 180 km/hr. I was looking at another problem.

anonymous · Answer

you have to figure out how far each went first

anonymous · Answer

180 km per hour for 45 minutes
how far did it go?

anonymous · Answer

Well 45 minutes is 3/4 of an hour:
180 km/hr * 3/4 = 135/4 or 33.75 km. If that's what you're asking. 

So I would also do that for the second plane going 240 km/hr?

anonymous · Answer

yes but your arithmetic is way off

anonymous · Answer

what is $$180\times \frac{3}{4}$$?

anonymous · Answer

looks like you divided by 4 twice or something

anonymous · Answer

Christ, lol 
I am looking at multiple problems and by mistake put 45 kl/hr multiplied by 3/4.

180 * 3/4 is 135 kl/hr.

anonymous · Answer

Also giving that 240 * 3/4 is 180

anonymous · Answer

ok so by pythagoras there distance is $$\sqrt{135^2+180^2}$$

anonymous · Answer

*their

Ah yes, 225. Thank you.
