You would have no trouble at all if the problem said "11 cows - 8 cows",
or "11 books - 8 books", or "11 cats - 8 cats", or "11 footballs - 8 footballs".
So why does it scare you when the items being counted are 'm's ?
Oh ! Here's another beauty: 11 M&Ms - 8 M&Ms = ?
Bill's original ratio is like this...
6 to 10
You need to solve for this...
x to 15
You have to multiply both sides of the original ratio by 15...
6 times 15 = 90
10 times 15 = 150
Your new ratio is 90 to 150
Which reduces to 3 to 5
Yout new ratio is 3 to 5
Answer:

Answer:
17 kilometers
Step-by-step explanation:
The pythagorean theorm is a^2 + b^2 = c^2
In this problem we can call 8 km a and 15 km b.
Plug 8 and 15 into the pythagorean theorm to get 8^2 + 15^2 = c^2
This will give you 289=c^2
Take the square root of both sides to get c=17
Hope this helps!
