Question

A carrage moves 30 km in 1 hr , so calculate its speed in meter per second

Answer 1

Speed=distance /time

distance =30km=30*1000=30,000m

time=1hr=1*3600s=3600

Speed=30,000/3600

=50/6m/s

=8.33 m/s

Hope it helps.....

plse mark me as brainliest....

Answer 2

Distance moved by carrage =30km =30000 Time taken =1hr= 3600 we know that speed = Total distance travelled/Total time taken so, speed = 30000/3600= 8.3m/s
