It would take 1.16 h for the runner to finish the race .
Step 1. Convert kilometres to miles.
11 km × (0.621 mi/1 km) = 6.83 mi
Step 2. Calculate the time.
Time = 6.83 mi × (1 h/5.7 mi) = 1.16 h
Answer: 1.199 hour runner will require to cover the 11 km .

Distance covered by runner = 11 km = 11 × 0.6213 miles = 6.8343 miles
1 km = 0.6213 mile
Speed of the runner = 5.7 mile/hour
[tex]speed=\frac{distance}{time}[/tex]
[tex]5.7 mile/hour=\frac{6.8343 miles}{time}[/tex]
[tex]time=\frac{6.8343 miles}{5.7 mile/hour}=1.199 hour[/tex]
1.199 hour runner will require to cover the 11 km .
