Answer 2

Solution :-

i).

$\implies \: speed \: = \frac{distance}{time}$

$\implies \: s = \frac{d}{t}$

$\implies \: d = s \: \times \: t$

ii).

$\implies \: simple \: intrest = \frac{principal \: \times \: rate \: \times \: time}{100}$

$\implies \: s.i. \: = \frac{p \: \times \: r \: \times \: t}{10}$

$\implies \: p \: \times \: r \: \times \: t \: = s.i. \: \times \: 100$

$\implies \: p = \frac{s.i. \: \times \: 100}{r \: \times \: t}$

$\implies \: r \: = \frac{s.i. \: \times \: 100}{p \: \times \: t}$

$\implies \: t \: = \frac{s.i. \: \times \: 100}{p \: \times \: r}$
