Question

light travel at a speed of 3,00,000km sec find a distance it cover in a week?​

Answer 1

Answer:

distance covered

1 sec = 300000km

1 min=300000×60km

1hr=300000×3600km

24 hr= 300000×3600×24 km

24×7 hr in a week=300000×3600×24×7km

Answer 2

Step-by-step explanation:

distance covered in a sec=3,00,000

distance covered in a minute=3,00,000*60

distance covered in an hour=3,00,000*60*60

so distance covered in a day=3,00,000*60*60*24

therefore distance covered in a week =3,00,000*60*60*24*7
