Answer:
Miguel start to swim when Ario has traveled 4.4 m.
Step-by-step explanation:
The total lenght of the pool is 25.
Since both of them standing 3 m from one side of the pool, then, the total distance both need to cover is [tex]25-3[/tex] m= 22 m.
Assume that the distance traveled by Ario before Miguel start to swin is [tex]x[/tex]. That means, the remaining distance to Ario (to cover the total size of the pool) is [tex]22-x[/tex].
Then, in acoordance to the problem, the ratio between these two distances must be equal to 1/4.
That is,
[tex]\frac{x}{22-x}=\frac{1}{4}[/tex] .
So, we need to obtain [tex]x[/tex] from this equation. We must note that [tex]x\neq 22[/tex], otherwise we have a zero in the denominator.
So, we rearrange the equation,
[tex]4x=22-x[/tex] (Multiplying both sides of equation by ([tex]4(22-x)[/tex]).
Then, [tex]5x=22[/tex].
Therefore, [tex]x=4.4[/tex] m.
Answer:
7.4
Trust me i took the test and chose 4.4 and it said it was wrong they said the answer was 7.4 so chose that for your sake the tutor got it wrong
