Question

4. a. The distance between the Earth and the Sun is
1.5 x 10 power 8 km. Find the square of this distance and
write it in standard form.​

Answer 1

Answer:

Since speed = distance/time,then time = distance/speed.Remember to convert the distance units to the same unit.1.5x108 km x(1000m/1km) = 1.5x1011 mThen (1.5x1011 m)/(2.997x108 m/s) = 500 seconds
