Answer #1

Given speed: 342 metre/sec

Convert to: kilometre/hour

Solution:

Converting 1 metre to kilometre :1metre = 10-3 km

Converting 1 sec to hour =

Therefore, we can imply, 1metre/sec=

  

Therefore, 1 metre/sec equals 3.6km/hour.

Therefore, 342metre/sec is equal to   .

Answer:

342metre/sec = 1231.2 km/hour.
