Answer 1

$\huge\sf\fbox\red{verified answer}$

The signal travels in a straight line, the distance between the spaceship and the ground station is equal to the total distance travelled by the signal. 5 minutes = 5*60 seconds = 300 seconds. Speed of the signal = 3 × 108 m/s. = 9*1010 meters.

Answer 2

Given that

The signal travels in a straight line, the distance between the spaceship and the ground station is equal to the total distance travelled by the signal.

Find out

The distance of the spaceship from the ground station

Solution

5 minutes = 5*60 seconds = 300 seconds.

Speed of the signal = 3 × 10⁸ m/s.

Therefore, total distance = (3 × 10⁸ m/s) * 300s

= 9*10¹⁰ meters.
