A basketball player spent 6 hr watching game films, practicing free throws,
and lifting weights. He spent twice as much time lifting weights as
practicing free throws and 2 hr longer watching game films than practicing
free throws. How many hours did he spend on each task?

Respuesta :

Answer:

3 hours watching game films.

1 hour practicing free throws.

And 2 hours lifting weights.

Step-by-step explanation:

Let's let G denote the amount of time spent watching game films,

F denote the amount of time spent practicing free throws, and

W denote the amount of time spent lifting weights.

We know that he spent a total of 6 hours watching films, practicing throws, and lifting weights. So, we can write that:

[tex]G+F+W=6[/tex]

We also know that he spends twice as much time lifting as practicing his throws. So, the time spent lifting W will be 2 times the time spent practicing free throws. In other words:

[tex]W=2F[/tex]

We also know that he spends 2 hours longer watching game films that practicing free throws. Therefore:

[tex]G=2+F[/tex]

This is a system of equations. We can solve using substitution.

Let's substitute the second and third equation all into the first. This gives us:

[tex](2+F)+F+(2F)=6[/tex]

Let's solve for F. Combine like terms:

[tex]4F+2=6[/tex]

Subtract 2 from both sides:

[tex]4F=4[/tex]

Divide both sides by 4:

[tex]F=1[/tex]

So, the basketball players spends 1 hour practicing free-throws.

Since we know that he spends twice as much time lifting weights than practicing free-throws, this means that he spends 2(1) or 2 hours lifting weights.

And he spends two hours longer watching game films. So, he spends 2 + 1 or 3 hours watching game films.

Therefore, he spends 3 hours watching game films, 1 hours practicing his free-throws, and 2 hours lifting weights.

And we're done!

Answer:

3 hours watching game films, 1 hour practicing free throws, and 2 hours lifting weights. Person above me is correct! :)
