Question

Convert the following speeds. 35 m/s into km​

Answer 1

Answer:

126km/h

Step-by-step explanation:

18/5*35=18*7=126km/h

Answer 2

ANSWER : At first convert metre into Km and second into minute and then minute into hour. We know that, 1000m=1Km. So, 1 metre=1/1000=10^-3 Km.

Now, 60sec=1 minute;1 sec=1/60 minute. Again 60 minute=1 hour ; 1/60 minute =

1/(60*60)= 1/3600 hour. Putting these values we get (35*10^-3)/(1/3600)= 126nKm/hour.
