Question

if the speed of train is 108 km per hour find the speed in minute per second and hence find out the distance travelled in 20 second​

Answer 1

Answer:

Speed of train = 108 km/ hr

Speed of train ( m/ s) = 108 × 1000 / 60 × 60

= 30 m/s

Distance travelled in 1 second = 30 m

Distance travelled in 20 seconds = 30 × 20

= 600m

Hope it helps.....

Answer 2

Answer:

Here is your answer :

To convert km/h to m/s multiply the speed with 5/18

$108 \times \frac{5}{18} = 30m \: per \: sec$

$distance = speed \: \times time \\ = 30 \times 20 \\ = 600m$
