Answer 1

Answer:

t = 130s

Step-by-step explanation:

$s = 3.9 * 10^{7} km$

$v = 3 * 10^{5} km/s$

$t = ?$

$t = \frac{s}{v}$

$t = \frac{3.9 * 10^{7} km}{3 * 10^{5}km/s }$

$t = 130 s$

If the speed signal sent was actually less, meaning that it would take more time to signal arrives from Earth to Mars. The lower the speed, the higher the time.
