Question

a car travels 20 kilometre in 20 minutes find the speed of car a kmh-1 b ms-1​

Answer 1

Answer:

Here's your answer

Explanation:

Given=> Distance (d) = 20km = 5.5m/s

              Time (t) = 20min = 1200sec

              Speed (s) = ?

we know that

speed = distance/time

s = 5.5/1200

s = 0.004m/s

s=0.004km/h

Answer 2

Question :

A car travels 20 kilometres in 20 minutes. Find the speed of the car in km/h and m/s.

-----------------

Given :

• Distance = 20 kilometers
• Time = 20 minutes

To find :

• Speed of car in km/h and m/s

Solution :

⇒ ​Now, let's convert minutes to hours.

[1 hour = 60 minutes]

20 minutes = 20/60 hours

         = 1/3 hours

Speed = Distance/Time

     = 20/(1/3)

     = 60

Therefore, the speed of the car is 60 km/hr.

⇒ Now, we have to convert the kilometers to meters.

[1 km = 1000 m]

20 kilometers = 20 × 1000

                       = 20000 meters

⇒ Next, we have to convert the minutes to seconds.

[1 minute = 60 seconds]

20 minutes = 20 × 60

                   = 1200 seconds

Speed = Distance/Time

     = 20000/1200

     = 1.67

Therefore, the speed of the car is 1.67 m/s.
