Question

Signal from spaceship reached ground in 5 min what was distance of spaceship from ground signal travel at speed of light 3 *10*8ms-1

Answer 1

Answer:

9×10^10m

Explanation:

Distance=Speed×Time

= 3×10^8(300 sec)

= 9×10^10 m

Answer 2

Answer:

5 min = 5 x 60s = 300 seconds

Distance = speed x time

Distance = 3 x 10^8 m/s x 300s

= 9 x 10^10 m

Or Distance = 90 million kilometers
