Question

A covers a distance of 2500m in 2hours. Calculate its speed in km/h.​

Answer 1

Answer:

Speed = distance/time taken

= 2500m = 2.5 km

= 2.5/2

=1.25km/h

Answer 2

Answer :

$\bullet$ Speed of the car is 1.25 km/h.

Given :

• Distance covered by the car = 2500 m
• Time taken = 2 hours

To Find :

• Speed of the car in km/h.

Calculation :

Here, we are given that distance covered by the car is 2500 m, so in order to calculate the speed, firstly we need to convert this [2500 m] into kilometre.

Divide 2500 m by 1000 to get the result in km.

→ 2500/1000

→ 2.5 km

Hence, distance covered by the car is 2.5 km.

Now, according to the question, let's calculate the speed of the car.

We know that,

• ${\underline{\boxed {\bf \purple {Speed = \dfrac{Distance}{Time}} }}}$

$\dag$ Putting the values,

$: \implies \sf Speed = \dfrac{Distance}{Time}$

Where,

• Distance = 2.5 km
• Time = 2 hours

$: \implies \sf Speed = \dfrac{2.5}{2}$

⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀⠀

$: \implies{ \boxed{\sf Speed = 1.25 \: km/h}} \pink{ \bigstar}$

Therefore,

• Speed of the car is 1.25 km/h

Extra Information:

• The SI unit of time is second.

• The SI unit of speed is m/s.

$\star$ Formula for finding time :

• ${\underline {\boxed {\large {\rm \pink { Time = \dfrac{Distance}{Speed}} }}}}$

$\star$ Formula for finding distance :

• ${\underline {\boxed {\large {\rm \pink { Distance = Speed \times Time }}}} }$

• Speed is the distance covered by the body in unit time. A body can move slow or fast.

• A speedometer & odometer indicates the speed of a vehicle.
