8.3 seconds
1.2 × 10^–1 seconds
1.08 × 10^16 seconds
10.8 × 10^15 seconds

All you need to solve this question is this equation : time = distance / velocity; time = 3.6 x 10^7 / 3 x 10*8; time = 0.12 seconds

pooja195 · Answer

but there is no 0.12

anonymous · Answer

if theres no 0.12 then how is that the answer...

jim_thompson5910 · Answer

you have to convert to scientific notation

jim_thompson5910 · Answer

0.12 is not in scientific notation

anonymous · Answer

so its A?

jim_thompson5910 · Answer

0.12 converts to 8.3 in scientific notation?

jim_thompson5910 · Answer

how do you jump from 0.12 to 8.3

anonymous · Answer

I meant B lol

jim_thompson5910 · Answer

hopefully you see how 0.12 = 1.2 x 10^(-1)

anonymous · Answer

i do, which is why i chose that one lol.
