Question

A car cover a distance 10km in5 minute calculate the speed of a car in centimeter per seconds and meter per second ​

Answer 1

1km=1000m

10km=10000m

1m=100cm

10000m=1000000cm

1min=60sec

5min=60*5=300sec

speed=d/t

incm

1000000/300=33333.33333cm/s

in m/s

s=10000/300=33.333m/s

Answer 2

Speed in m/s :

Distance covered by car = 10 Km

Distance covered by car in metres = 10 * 1000 = 10000 metres (since 1 km = 1000 m)

Time taken = 5 minutes

Time taken in seconds = 5 * 60 = 300 seconds

Speed (m/s) = Distance covered/Time taken

= 10000/300

= 100/3 m/s

Speed in m/s = 33 1/3 m/s

Speed in cm/s :

Distance covered by car = 10 Km

Distance in centimetres = 10 * 100000 = 1000000 cm (1 Km = 1000000 cm)

Time taken in seconds = 5 * 60 = 300 seconds

Speed in cm/s = Distance covered/Time taken

= 1000000/300

= 10000/3

Speed in cm/s = 3333 1/3 cm/s

Therefore speed of the car are 33 1/3 m/s or 3333 1/3 cm/s in m/s and cm/s respectively.
