Answer 2

1 km = 1000 m

so, 250 km = 250*1000 = 2,50,000 m

using the above formula,

1000m = 1km

so, 1m = 1/1000 km

so, 540m = 540/1000 = 0.54km

1 hrs = 60 minutes

6 hrs = 6*60 = 360 minutes

1 minute = 60 seconds

360 minutes =360*60 = 21600 seconds

using above formula,

60 seconds = 1 minute

3600 seconds = 3600 / 60 = 60 min

60 min = 1 hr

60 minutes = 60/60 = 1 hr

for converting to km/hr ,

multiply it by 5/18

so, 140*5/18 = 60 km/hr

using the above formula,

4.5*60 = 27 seconds

and ,

4.5*1/60 = 0.075
