Step-by-step explanation:

Given

Scott run 20 km in 85 minutes

Speed is given by

$\Rightarrow \text{speed}=\dfrac{\text{distance}}{\text{time}}$

Speed of Scott

$\Rightarrow v=\dfrac{20}{\frac{85}{60}}=\dfrac{20\times 60}{85}=14.117\ km/hr$

For 52 km, time taken is

$\Rightarrow \text{time t}=\frac{52}{14.117}=3.683\ hr\ or\\\Rightarrow t=221\ min$
