Convert 2536 mm/min to m/s. Use dimensional analysis.

Deffense [45]

Answer:

As we know that, 

1 mm/min = 1.66667E-5 m/s
1 m/s = 60000 mm/min

Now, come to the question - 

$\\ \implies \sf \: 2536 \times 1.66667E-5 m/s \\ \\ \\ \implies \sf \blue{0.0422666667 \:m/s } \\$

Result : 2536 mm/min = 0.0422666667 m/s.
