A boy has to cover 20 Km in 2 h. What should be his speed?

Answer 1

answer =10km/hr

Explanation:

speed formula =d/t

=20/2

=10km/hr

Answer 2

$\large\underline{\underline{\maltese{\red{\pmb{\sf{\: Given :-}}}}}}$

• ➬ Distance covered = 20 km
• ➬ Time taken = 2 h

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\large\underline{\underline{\maltese{\gray{\pmb{\sf{\: To \: Find:-}}}}}}$

• ➬ Speed = ?

▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬▬

$\large\underline{\underline{\maltese{\purple{\pmb{\sf{\: Solution :-}}}}}}$

❒ Formula Used :

$\large{\blue{\bigstar}} \: \: {\underline{\boxed{\red{\sf{Speed = \dfrac{Distance}{Time}}}}}}$

➢Here :

• ➳ Speed = ?
• ➳ Distance = 20 km
• ➳ Time = 2 h

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

❒ Finding the Speed :

$\qquad{\hookrightarrow{\sf{ \: \: Speed = \dfrac{Distance}{Time}}}}$

$\qquad{\hookrightarrow{\sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \dfrac{20}{2}}}}$

$\qquad{\hookrightarrow{\sf{ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \cancel\dfrac{20}{2}}}}$

$\large{\qquad{\green{:\longmapsto{\underline{\boxed{\sf{ 10\: km/h}}}}}}{\pink{\bigstar}}}$

$\qquad{━━━━━━━━━━━━━━━━━━━━━━━━━━}$

❒ Therefore :

❝ Speed of the boy is 10 km/h . ❞
