Let
x------> <span>speed on the bicycle
y------> </span><span>speed walking
we know that
</span>x=6+y------> equation 1<span>
speed=distance /time-------> time=distance/speed
1/y=2.5/x-------> y=x/2.5------> x=2.5y-------> equation 2
equals 1 and 2
6+y=2.5y-----> 2.5y-y=6------> 1.5y=6-----> y=6/1.5-----> y=4 mi/h
x=6+y-----> x=6+4-----> x=10 mi/h
the answer is
the speed walking is 4 mi/h

Equal ratios are those that are equal to each other.
Example:-
4/2 = 8/4
Also, ratios compare to values, and there are 3 ways to write a ratio.
4/2 and 4:2 and 4 to 2
Hey there! :D
To find the geometric mean, you multiply the numbers and then find the square root.
12*3= 36
The square root of 36 is 6.
The geometric mean is 6.
I hope this helps!

<span>1. </span><span>So we have the system of
equation. (4, -3)
let’s create another system of equation.
Let a = 4
and Let b = -3
First equation
=> Let’s pick any numbers to be used. Let’s have number 5
=> 5a + 5b
=> 5 (4) + 5 (-3)
=> 20 + (-15)
negative and positive is equals to negative
=> 20 – 15
=> 5 (this the first value of our equation, let this be the value of X)
Second
=> Pick another number, Let’s have 6
=> 6a + 6b
=> 6 (4) + 6 (-3)
=> 24 + (-18)
=> 24 – 18
=> 6 (this is the value of our second equation, let this value be Y)
Now, we have (A, B) = (4, -3) and (X, Y) = (5,6)</span>
