Answer 1

Question:-

A man walks 8 km in 1 hour 20 minutes. What is the speed of the man in km/hr?

Given:-

A man walks 8 km in 1 hour 20 minutes.

To Find:-

What is the speed of the man in km/hr?

Solution:-

⇒$\sf\red{1hr=60min}$

⇒so,1hr 20min = 60+20min

⇒1hr 20min = 80mins

_____________________

so,the man's speed = 8000m per 80mins

➺so the man's speed per 1min = $\cancel\frac{8000}{80}$

➺the man's speed per 1 mins = 100m

__________________________________________

$\\ \\ ⟼speed \: p hr = 100 \times 60meters \\ \\ ⟼speed \: p hr \: = 6000meters \: \: \: \: \: \: \\ \\ \blue {\underline{ \boxed{ \purple {\mathfrak{\therefore \: the \: speed \: of \: the \: man \: is \: 6km \: phr}}}}}$
