The 1st 3 members of the stilt walking relay team finished their laps of the race with the mean time of 53 seconds per lap what meantime for the next 2 members will give an overall Team mean of 50 seconds per lap?

Sagot :

we can use an average between the first 3 and the second 2 and the average must be 50 so

[tex]\frac{53+x}{2}=50[/tex]

where x is the time of the seconds 2 runners

now we solve x

[tex]\begin{gathered} 53+x=50\times2 \\ x=100-53 \\ x=47 \end{gathered}[/tex]

the time of the second runners must be 47 seconds per lap
