Answer: 1) 0.2083 minute
Step-by-step explanation:
Given : Dan took 12.5 seconds to run the 100 meter dash.
We know that 1 minute = 60 seconds
⇒ 1 second = [tex]\dfrac{1}{60}[/tex] minute
Then , the 12.5 seconds =[tex]\dfrac{12.5}{60}\text{ minute}[/tex]
[tex]=0.208333333333\approx0.2083\text{ minute}[/tex]
1 hour= 60 minute
⇒ 1 minute = [tex]\dfrac{1}{60}[/tex] hour
Then, [tex]0.2083\text{ minute}=\dfrac{0.2083}{60}\approx0.00347[/tex]
hence, the correct answer is 0.2083 minute.
