Answer 1

QUESTION :

during 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 3×10^8m

GIVEN :

• time taken = 5 min

(in order to convert it into seconds multiply by 60)

time taken = 5 × 60 = 300 sec

• Speed = 3 × 10 ^ 8 m / s ²

SOLUTION :

Velocity = Distance covered / time taken

Distance = Velocity × time taken

Distance = 3 × 10^8 × 300

Distance = 9 × 10^ 10 m

Answer 2

Given:

During an experiment,a signal from a spaceship reached the ground station in 5minutes and the signal travels at the speed of light which is 3×10⁸m/s.

To Find:

The distance of the spaceship from the ground station.

Solution:

Speed of the signal (v) = 3×10⁸m/s

Time taken (t) = 5 minutes = 5×60 s

Distance (s) = ?

We know,

Speed = distance/ time

i.e. v = s/t

or, s = v×t

or, s = 3×10⁸m/s × 5 × 60 s

or, s = 900 × 10⁸ m

or, s = 9 × 10¹⁰ m

Thus, The Distance of the spaceship from the ground station is 10¹⁰ m.
