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

It is known that the speed of a cyclist is 3 m / s.
Let’s express distance in terms of speed and time: distance = speed * time. Let’s translate this time (1.5 hours) into seconds, since all quantities must have one unit of measurement. It is known that 1 hour is equal to 3600 s. Hence, half an hour = 1800 s. Therefore, 1.5 hours = 3600 s + 1800 s = 5400 s.
The desired distance = 3 m / s * 5400 s = 16200 m = 16.2 km (since 1 km = 1000m).
Answer: a cyclist can travel 16.2 km
