A space probe on the surface of mars sends a radio signal back to earth,a distance of 7.19 ×10⁷ km. Radio travel at the speed of
lys-0071 [83]

Answer:

240 seconds

Explanation:

Data Given:

Distance Radio travel to earth = 7.19 ×10⁷ km

Speed of this radio signal = 3.00 ×10⁸ m/s

Solution:

First convert Km to m

1 km = 1000 m

7.19 ×10⁷ km = 7.19 ×10⁷ x 1000 = 7.19 × 10¹⁰m

Formula used to calculate time

            Speed (S) = distance (d) / time (t)

rearrange above equation for time

            time (t) = distance (d) / Speed (S) . . . . . . . . .(1)

Put values in equation 1

            time (t) = 7.19 × 10¹⁰/ 3.00 ×10⁸ m/s

            time (t) = 240 s

So 240 seconds it take for the signal to reach the earth
