Question

Using the speed formula calculate the speed of a person in kilometers per hour if the distance he travels is 40 kilometers in 2 hours?

Answer 1

${ \underline{ \underline{ \maltese{ \huge{ \textsf{ \textbf{ \pink{answer}}}}}}}}$

The formula for speed is:-

$\implies \bold \red{speed = \frac{distance}{time}}$

• Distance = 40 kilometers
• Time = 2 hours

$\implies \bold \blue{speed = \frac{40}{2} km/hour}$

$\longrightarrow \bold \green{20 \: kilometers \: per \: hour}$

Therefore, the speed of the person is 20 kilometers per hour.

Answer 2

⚝ Given:-            

• ➠ Distance = 40 kilometers
• ➠ Time = 2 hours

⚝ To Find:-          

• ➽ The speed of a person

⚝ Solution:-          

Here, we have the distance he travels is 40 kilometres and the time is of 2 hours.

So, we will use the speed formula

• $\large\boxed{\tt{Speed\:=\:\dfrac{Distance}{Time}}}$

Where,

• ➩ Distance = 40 kilometers
• ➩ Time = 2 hours

                     ____________

♡ On applying the formula ♡

$\qquad\tt{:\implies\:Speed\:=\:\dfrac{Distance}{Time}}$

$\qquad\tt{:\implies\:Speed\:=\:\dfrac{40\:km}{2\:hours}}$

$\qquad\tt{:\implies\:Speed\:=\:20\:km/hr}$

. ° . Thus, the speed of a person is 20km/hr if the distance he travels is 40 kilometers in 2 hours.
