You can ride a bicycle at a speed of 3 m / s without much stress. How far can you go in 1.5 hours?

V = 3 m / s.
t = 1.5 h = 5400 s.
S -?
With uniform rectilinear movement, the path S traversed by the body is determined by the formula: S = V * t, where V is the speed of uniform movement, t is the time of movement.
Let’s translate the time of movement in seconds. There are 60 minutes in 1 hour, and 60 seconds in each minute.
t = 1.5 h = 1.5 * 60 min = 90 min = 90 * 60 s = 5400 s.
S = 3 m / s * 5400 s = 16200 m.
Answer: you can ride a bike to a distance of S = 16200 m.
