Explanation:
Given that,
A student covered a distance of 210 meters in 35 seconds.
We need to find the student's speed in meters/second and also in meters/minute.
Speed, v = distance (d)/time (t)
So,
[tex]v=\dfrac{210\ m}{35\ s}\\\\=6\ m/s[/tex]
We know that, 1 minute = 60 seconds
[tex]6\dfrac{m}{s}=6\times \dfrac{m}{(\dfrac{1}{60})\ \text{minutes}}\\\\=360\ \text{meters/minutes}[/tex]
Hence, the student's speed is 6 m/s or 360 meters/minute.
