$\sf\large\bold{\orange{\underline{\blue{ Solution :-}}}}$

$\:\:$

As the given speed is in metre per second and the time taken is in minutes So we need to convert units

$\:\:$

$\underline{\bold{\texttt{Conversion of the units :}}}$

$\:\:$

1 Minutes = 60 Seconds

$\:\:$

20 Minutes = 60 × 20 Seconds

$\:\:$

20 Minutes = 1200 Seconds

$\:\:$

We know that ,

$\:\:$

➠ $\sf D = S \times T$ ⚊⚊⚊⚊ ⓵

$\:\:$

Where ,

$\:\:$

• D = Distance

• T = Time taken

• S = Speed

$\:\:$

$\underline{\bold{\texttt{For the given case :}}}$

$\:\:$

• D = D

• T = 1200

• S = 0.2

$\:\:$

⟮ Putting the above values in ⓵ ⟯

$\:\:$

➜ $\sf D = 0.2 \times 1200$

$\:\:$

➨ 240 Metres

$\:\:$

• Hence the Distance between her house and the school is 240 m
