Chemistry => Measurements => Metric Unit Conversions
We have a velocity value equal to 56.8m/min. Remember that velocity is defined as the distance traveled in a given time.
Now, we are asked to find the time it will take to walk 7900ft.
So we must do a conversion of units, to go from feet to meters we will take into account the following relationship
[tex]1ft=0.3048m[/tex]
So, the distance of 7900ft in meters will be:
[tex]m=7900ft\times\frac{0.3048m}{1ft}=2408m[/tex]
Now, the time that will take to cover this distance will be:
[tex]\begin{gathered} Velocity=\frac{Distance}{Time} \\ \\ Time=\frac{Distance}{Velocity} \\ \\ Time=\frac{2408m}{56.8m/min} \\ \\ Time=42.4min \end{gathered}[/tex]
We have to express the answer with 2 significant figures.
It will take 42 minutes to cover a distance of 7900ft
Answer: 42 min
