speed of first one is given as
[tex]v_1 = 1 mile \: in \: 1 min[/tex]
we also know that
1 mile = 1609 meter
also for time of motion
t = 1 min = 60 s
so in SI units the speed is given as
[tex]v = \frac{1609}{60}[/tex]
[tex]v = 26.82 m/s[/tex]
so 1 mile/min = 26.82 m/s
So here we will say that 1 mile per min is more speed than 20 m/s as we can see that 1 mile / min is 26.82 m/s in SI units after its conversion
