Calculate how many minutes it will take sunlight to reach the earth. Light travels at 3x10^8 m/s and the sun is 144 million km away.
Use the formula for time and remember to make the units same.

Answer 1

4.8×10^18

Step-by-step explanation:

distance=144 million km

time=?

speed=3×10^8 m/s

time =distance ÷ speed

144km÷3×10^8

144km into m

144000 million m ÷ 3×10^8 m( meter will cancel out on both sides)

144000000000÷3×10^8

4.8×10^18
