Answer 1

Answer:221 min

Explanation:

Given

Scott run 20 km in 85 minutes

Speed is given by

`\Rightarrow \text{speed}=\frac{\text{distance}}{\text{time}}`

Speed of Scott

`\Rightarrow v=(20)/((85)/(60))=(20* 60)/(85)=14.117\ km/hr`

For 52 km, time taken is

`\Rightarrow \text{time t}=(52)/(14.117)=3.683\ hr\ or\\\Rightarrow t=221\ min`
