$1000 m s$ $1000ms$

we will deal with the numerical and dimensional parts separately

$(1)$ $(1)" "$ numerical part

$\frac{60}{0.060}$ $60/0.060$

when dividing by a decimal the best approach is to multiply top and bottom by a power of $10$ $10$ in order to make the denominator a whole number.

$\frac{60}{0.060} \times \frac{100}{100}$ $60/0.060xx100/100$

$= \frac{6000}{6}$ $=6000/6$

$= 1000$ $=1000$

$(2)$ $(2) " "$ Dimensional part

$\frac{m s^{2}}{s}$ $(ms^2)/s$

change so that all dimensions are on top.

$= m s^{2} s^{- 1}$ $=ms^2s^(-1)$

use rules of powers

$= m s^{2 + - 1} = m s^{1} = m s$ $=ms^(2+ -1)=ms^1=ms$

put the two together

$= 1000 m s$ $=1000ms$
