Answer 1

Answer:

9 × 10 to the power 10 meters

Explanation:

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
