During an experiment, a signalfrom a spaceship reached theground station in five minutes.What was the distance of thespaceship from the groundstation? The signal travels at thespeed of light, that is, 3 x 108m s-.

Answer»

Time taken=5min=5×60s=300secspeed of signal u =3×10^8 m/sDistance=??we know thatspeed= Distance/timeDistance= Speed×Timeputting the valueDistance= 3×10^8 × 300Distance = 9×10^10m

Hello friend!!!

Your question is to find the distance of this distance of spaceship from the ground when the signal travelling at the speed 3 into 10 to the power 8 reach the ground after 5 minutes.

♦1 minute is equal to 60 seconds

♦5 minutes is equal to 60×5 seconds = 300 seconds

★So the distance = speed × time

= 300 × 3 ×10 to the power 8

=9 × 10 to the power 10 meters

★So the distance of the spaceship from the ground is 9 × 10 to the power 10 meters

yes this is a correct answer

distance=speed×timed=3×10^8×300d=9×10^10m

correct answer is 9×10^10m
