Question

Change the speed of 30m/s into km/h... Full explanation required!​

Answer 1

Answer:

108 kilometres per hour

30m/s

As we have to convert from smaller unit to bigger one so we have to divideas

m to km conversion is

1km=1000m

1m=1/1000km

so we will replace m by 1/1000km

s to hr conversion is

1hr=3600s

1s=1/3600hr

so we will replace s by 1/3600hr

Given is

30*m/s

30*1/1000km/1/3600hr

30*1/1000*3600hr

108km/hr
