Question

Find the speed of a if it travel 720 km in 6 hours

Answer 1

Answer

Speed of the body = 120 km/hr

Explanation :

Given :

• Distance travelled by the body = 720 km
• Time taken by the body = 6 hours

To find :

• Speed of the body

Knowledge required :

• Formula to find speed :-

⠀⠀⠀⠀Speed = d/t

[where : d is the distance travelled and t is the time taken to travel the distance.]

Solution :

⠀⠀⠀⇒ Speed = 720/6

⠀⠀⠀⇒ Speed = 120

Speed = 120 km/hr

________________________________

• Speed is the distance travelled by a body in a particular time.

• Its unit is km/hr or m/s.

• Distance is the path travelled by a body.

• Its unit is km or m.

• The unit of time is hr, seconds or minutes.

Some related formulae :-

• Formula to find distance :-

⠀⠀⠀Distance = Speed × Time

• Formula to find time :-

⠀⠀⠀Time = Distance/Time

Answer 2

Answer:

☆Given☆

• Distance travelled by the body = 720 km
• Time taken by the body = 6 hours

☆To find ☆

• Speed of the body

☆Formula☆

${ \underline{ \boxed{ \sf \: { \green{Formula \: to \: find \: speed \: = \bf \: \bf \: \: speed\rightarrow \dfrac{distance}{time}}}}}}\green{\bigstar}$

☆Understanding first☆

• A body travel 720 km
• The time is also given as 6 hrs so, simply find speed

☆SolutioN☆

$\rightarrow \: {\blue{ \sf\: speed \: = \cancel\dfrac {720}{6}}}$

${\huge \therefore} \: {\boxed{\purple{ \sf\:speed \: = 120 \: km \: per \: hour}} \: { \purple \bigstar}}$

☆More KnowledgE☆

• Speed is a distance per unit of time .
• S.I. unit of speed → km/s
