2 ³/₄ minutes.
Given:
Four members of a track team run a relay race in 165 seconds.
Question:
How many minutes did it take them to run the race?
The Process:
Recall these:
[tex]\boxed{ \ 1 \ minute = 60 \ seconds \ }[/tex]
We will convert 165 seconds into minutes.
[tex]\boxed{ \ = 165 \ seconds \times \frac{1 \ minute}{60 \ seconds} \ }[/tex]
We crossed out seconds.
[tex]\boxed{ \ = 165 \times \frac{1 \ minute}{60} \ }[/tex]
[tex]\boxed{ \ = \frac{165}{60} \ minutes \ }[/tex]
Both the numerator and denominator are divided by 15 to make it simpler.
[tex]\boxed{ \ = \frac{11}{4} \ minutes \ }[/tex]
[tex]\boxed{ \ = \frac{8}{4} + \frac{3}{4} \ minutes \ }[/tex]
[tex]\boxed{\boxed{ \ = 2\frac{3}{4} \ minutes \ }}[/tex]
Thus, they took 2 ³/₄ (two and three quarter) minutes to run the race.
