Answer 2

$\huge{ \underbrace{ \text{Question}}}$

A man runs at the speed of 20 km /hr . How much time will he take to cover 1500 metres?

$\huge{ \underbrace{ \text{Answer}}}$

Given:-

$\sf{ \rightarrow{A \: man \: runs \: with \: a \: speed \: of \: 20km/h}}$

To Find:-

$\sf{ \rightarrow{The \: time \: that \: will \: take \: to \: cover \: 1500 \: meters}}$

Solution:-

We know that,

1 hour = 60 minutes

And,

1 kilometer = 1000m

20 kilometers = (1000×20)m= 20000m

According to the question,

$\sf{20000 \: meters \: is \: coverd \: in \: 60 \: minutes}$

$\\ \sf{ \implies{1 \: meter \: is \: covered \: in \: \frac{60}{20000} minutes}}$

$\\ \sf{ \implies{1500 \: meter \: is \: covered \: in \: \frac{60 \times 1500}{20000} minutes }}$

$\\ \sf{ \therefore{1500 \: meter \: is \: covered \: in \: = \orange{4.5 \: minutes}}}$

$\underline{ \boxed{ \rm{Hence \: the \: answer \: is \: \bold{4.5 \: minutes}}}}$
