A space probe is 7.62 x 10 to the 7th power kilometers from the surface of the planet Mars. If the space probe is traveling towards mars at a arate of 127 meters per second, how many hours will it take the probe to reach the surface of the plant? Round to the nearest hour.

Its a math homework assignment
Ya this is math, not science
To find out how many hours it will take for the space probe to reach the surface of Mars, we need to convert the distance from kilometers to meters and then calculate the time it takes using the speed of the probe.
First, let's convert the distance from kilometers to meters. We can do this by multiplying the given distance by 1000:
7.62 x 10^7 kilometers * 1000 = 7.62 x 10^10 meters
Now we know the distance in meters. The speed of the probe is given as 127 meters per second. To calculate the time it takes, we can divide the distance by the speed:
Time = Distance / Speed
Time = (7.62 x 10^10 meters) / (127 meters/second)
Now, let's simplify the equation:
Time = 7.62 x 10^10 meters * (1 second / 127 meters)
Time = 6.007 x 10^8 seconds
To convert this time from seconds to hours, we divide by the number of seconds in an hour:
Time = (6.007 x 10^8 seconds) / (3600 seconds/hour)
Time ≈ 167083 hours
Now, we round the answer to the nearest hour:
Time ≈ 167,000 hours
So, it will take approximately 167,000 hours for the space probe to reach the surface of Mars.
