Velocity=distance/time

Data:
distance=10 Km=10 km*(0.621 miles/1 km)=6.21 miles.
time=55 minutes

Velocity=6.21 miles/55 minutes=0.11290909... miles/minute≈0.113 miles/ minute

Data: 
distance=1 mile.
velocity=0.113 miles/minute

time=distance /velocity
time=(1 mile) / (0.113 miles/ minute)=8.85668... minutes≈8.86 minutes.
