I know the answer is 7.3 km, but how do you get that answer?

  • anonymous
have you learnt Pythagoras theorem?

A little bit yeah

I still get easily confused by this stuff, anything math related I'm usually garbage at :b

so what we do, we want to know the horizontal length and the vertical length that corresponds to both points

so apply pythagoras theorem to determine the hypotenuse (the distance between the two points)
anonymous
  • anonymous
we always imply that the distance of two points is always the quickest/shortest distance
anonymous

\[a ^{2}+b ^{2}=c ^{2}\] where a is one side length, b is the other side length and c is the hypothenuse length

so would it be 2+8=c?
anonymous
  • anonymous
remember each term is squared
anonymous
  • anonymous
4+64=c ?
anonymous
  • anonymous
even the c term is squared! haha
anonymous
  • anonymous
oops. i made a mistake, the vertical length is not 8 units long
anonymous
  • anonymous
it should be 7

4 + 49 = c (squared) then add 53 = c (squared)
anonymous
  • anonymous
yep! now just square root both sides to find the answer
anonymous
  • anonymous
7.280 from my calculator, so 7.3 km
anonymous
  • anonymous
\[c ^{2}=54\] \[\sqrt{c ^{2}}=\sqrt{54}\] \[c=\sqrt{}\]
anonymous
  • anonymous
yep! awesome job

Awesome, thank you! :)

no problem. fan and medal if you need help another time
