What is the rate in meters per second of a jetliner this is travelling at a rate of 846 km/h

Answer 1

useful conversion:
1 km = 1000 m
1 hr = 60 min = 60*60 s

*note: you can rewrite 846 km/hr into:
(846 km)*(1/hr)
thus, using dimensional analysis to cancel units,
(846 km)*(1000 m / 1 km) = 846*1000 m
(1/hr)*(1 hr / 60*60 s) = 1 / 60*60 s

now multiply both:
846*1000 * 1/(60*60) = ?

hope this helps. :)
