To find the number of hours it will take for the asteroid to hit Mars, we can divide the distance between the asteroid and Mars by the speed of the asteroid:
Number of hours = Distance / Speed
Number of hours = (3.311×10^8 mi) / (7.7×10^4 mi/hr)
We divide the distance 3.311×10^8 mi by the speed 7.7×10^4 mi/hr:
Number of hours = (3.311 / 7.7) * 10^(8-4) hours
Number of hours = 0.42948 * 10^4 hours
Expressing this in scientific notation to the exact decimal place gives:
Number of hours = 4.2948 × 10^3 hours
An asteroid is heading toward Mars at the rate of 7.7×104 mi./hr. If the asteroid is 3.311×108 miles away from Mars, how many hours will it be before it hits Mars? Write the answer in scientific notation, expressed to the exact decimal place.(1 point)
