Question

a man runs at the speed of 10 kilometres per hour how much time will he take to cover 750 metres?​

Answer 1

Answer: 0.075 hours or 4.5mins

Explanation:

speed of man = 10km/h

speed = distance/time

Therefore, time = distance/speed

To find : time

Given, distance = 750m = 0.75km

So, time taken = 0.75/10 = 0.075 hours or 4.5min

Answer 2

$\frak{\red{Given}} \begin{cases} \sf{\orange{ A\; man \;runs \;at \;the \;speed \;of\; 10 \;km/hr}}\\\sf{\orange{Distance = 750 m}}\end{cases}$

$\frak{\red{To\;Find:\;}} \sf{\orange{How~ much ~time ~will ~he ~take ~to ~cover ~750 ~metres.}}$

$\LARGE{\frak{\red{Solution}}}$

• Speed = 10 km/hr
• Distance = 750 m

Converting meter into kilometre:

➨ $\sf 750 m = \dfrac{750}{1000} = 0.75 km$

★ Formula used:

$\boxed{\sf{\orange{Time = \dfrac{Distance}{Speed} } } }$

$\implies \sf {\orange{Time = \dfrac{0.75}{10}}}$

$\implies \sf {\orange{Time = 0.075}}$

Converting into seconds,

$\implies \sf{\orange{0.075 \times 60 \times 60}}$

$\implies \sf{\orange{0.075 \times 3600}}$

$\implies \sf{\orange{\underline{270\;seconds}}}$

∴ 270 seconds time will take to cover 750 meter.
