In Ashford is heading towards Mars at a rate of 7.7 * 10 ⁴ mi./hr. If the asteroid is 3.311 * 10 ⁸ miles away from Mars how many hours will it be before it hits Mars right to answer and scientific notation expressed to the exact decimal place

1 answer

To find the time it will take for the asteroid to reach Mars, we need to divide the distance to Mars by the speed of Ashford:

Time = Distance / Speed

Time = (3.311 * 10^8 miles) / (7.7 * 10^4 mi./hr)

When dividing numbers written in scientific notation, we subtract the exponents:

Time = 3.311 * 10^(8-4) / 7.7

Time = 3.311 * 10^4 / 7.7

Now, dividing the numerical values:

Time = 429.7402

We can express this answer in scientific notation:

Time = 4.297402 * 10^2 hours

Therefore, it will take approximately 4.297402 * 10^2 hours for the asteroid to hit Mars.
