Answer:
Scott will take 221 minutes to run 52 km
Step-by-step explanation:
Speed
The speed of an object can be calculated with the formula:
[tex]\displaystyle v=\frac{d}{t}[/tex]
Where d is the distance traveled and t is the time taken.
Scott can run d=20 km in 85 minutes. Thus, his speed is:
[tex]\displaystyle v=\frac{20}{85}\ km/min[/tex]
Now he wants to know how many minutes it will take him to run d=52 km. Solving the formula for t:
[tex]\displaystyle t=\frac{d}{v}[/tex]
Since the speed has been already determined:
[tex]\displaystyle t=\frac{52}{\frac{20}{85}}[/tex]
Multiplying by the reciprocal of the denominator:
[tex]\displaystyle t=52*\frac{85}{20}[/tex]
t = 221 min
Scott will take 221 minutes to run 52 km
