Question

A man runs at the speed of 9 m/s. How much time will he take to cover 750 meters?

Answer 1

$\longrightarrow\underline{\underline{\red{\sf{solution}}}}$

$\sf \: speed \: of \: the \: man = 9m/s$

$\sf \: time \: taken \: to \: cover \: 750 \: meters = x$

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

$\implies \sf \: \frac{750}{9} \times \frac{18}{5} \: m/s$

$\sf\implies \: \frac{15}{1} \times \frac{2}{1}$

$\sf \implies \: 15 \times 12$

$\sf \implies180 \: m/s$

$\sf∴if \: a \: man \: runs \: at \: the \: speed \\ \sf \: of \: 9 m/s . 180 \: secs \: he \: will \: take \\ \sf to \: cover \: 750 \: meters.$

Answer 2

83.33second.☑

Step-by-step explanation:

Given⤵

➡A man run at speed of 9m/s.

To find⤵

➡Time taken by man cover 750m.

Solution⤵

$⚫Using\:distance\:formula\\ Distance= Speed×time\:, we\:get \\Time=\frac{Distance}{Speed}\\➡Time=\frac{750}{9}\\➡Time=83.33s\\✅Hence\:83.33s\: is \:taken \:to\:complete\\750m \:if\:the \:speed\:is\:9m/s.$

Extra Points⤵

$✡Distance=Speed×Time\\✡Speed=\frac{Distance}{Time}\\✡Time=\frac{Distance}{Speed}$

Hope this is helpful to you!
