Question

during an experiment,a signal from a spaceship reached the ground station in five minutes,what was the distance of the spaceship from the ground station?the signal travels at the speed of light that is 3X10to the power 8 meter per seconds

Answer 1

Time taken=5min=5×60s=300sec
speed of signal u =3×10^8 m/s
Distance=??
we know that
speed= Distance/time
Distance= Speed×Time
putting the value
Distance= 3×10^8 × 300
Distance = 9×10^10m

Answer 2

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

HOPE THAT HELPS.... ☺️
