Answer:

Step-by-step explanation:
Use the distance formula!

If we plug in the coordinates:

That's our answer!
Answer=8/9
16/18=8/9
if you divide 16 and 18 by 2, you get 8 and 9
Simple equation and only requires one step to solve. Remember, a number and a variable juxtaposed means multiplications.

One step? I know. It seems more because I was slowing down the calculations for you so could understand everything happening. For someone who can do this in their sleep it would, for them, take one step.
I = PRT....rearrange
I / PR = T
I = 360
P = 1800
R = 10% = 0.1
I/PR = T
360 / (1800*0.1) = T
360 / 180 = T
2 = T...so it would take 2 years
