Light from the sun can travel a million miles in 5.368 second
In case of rounding to nearest tenth, we check the digit in hundredths place.
if it is equal to or greater than 5, we increase the digit in tenths place by 1
if it is less than 5 , we keep the digit in tenths place same
5.368 , here digit in hundredth place is 6, which is greater than 5, so rounding off we get 5.4
Answer is 5.4 seconds
