Average length of all the 10 children's finger is (8.1×10) cm = 81 cm.

  • The mean length of 11 adult's big finger is 14.1 cm

The speed of light is 186,182 miles per second. How many miles can light travel in a non-leap year? Express your answer in scien
zepelin [54]
So theres 366 days in a leap year, 
you need to find hours, minutes, and then seconds
366 x 24 = 8,784 hours 
8,784 x 60 = 527,040 minutes
527,040 x 60 = 31,622,400 seconds
31,622,400 seconds x 186,182 mps = 5.88 x 10^10 
therefore light travels 5.88 x 10^10 in one leap year
