A hockey puck is sliding on frictionless ice on an infinite hockey rink.
Its speed is 36 km/hour. How far does the puck slide in 10 seconds ?

(36 km/hr) x (1,000 m/km) x (1 hr/3600 sec) x (10sec) =

(36 x 1,000 x 10 / 3,600) meters = 100 meters

What is the puck's speed in miles per hour ?

(36 km/hr) x (0.6214 mi/km) = 22.37 mi/hr
