Question

How long does it take a person to skate the width of a hockey rink (85 feet) at a constant speed of 15 feet per second?

Answer 1

S(travel distance)=85 ft
v (velocity)=15 ft/s
-----------------------------------
t (time)=?

Calculate the time with the formula for the velocity:
v=S/t
t=S/v
t=85 ft/(15 ft/s)
t=5.666s
