Answer:

We can use the formula:

distance = rate x time

to solve this problem. We are given the distance (500 km) and the rate (120 m/s), and we want to find the time.

However, we need to make sure that the units are consistent. The distance is given in kilometers (km), so we need to convert it to meters (m):

500 km = 500,000 m

Now we can plug in the values and solve for time:

500,000 m = 120 m/s x time

time = 500,000 m ÷ 120 m/s

time ≈ 4166.67 seconds

Therefore, it will take approximately 4166.67 seconds (or 69.44 minutes) for the satellite to travel 500 km at a rate of 120 m/s.
