convert 8 min into sec
therefore total time 500 sec
now speed of light 3*10^8m/s
ATQ it is 1unit
there fore for 500 sec it would be 500 unita

Answer - 500 units
no. of units = no of seconds
1 unit = distance travelled by light in 1 sec
x units = distance travelled in x sec.
x = 8×60 +20 = 500
no. of units = no of seconds
1 unit = distance travelled by light in 1 sec
x units = distance travelled in x sec.
x = 8×60 +20 = 500
