To find the number of hours it will take for the asteroid to hit Mars, we need to divide the distance by the rate.
distance = 3.311*10^8 miles
rate = 7.7*10^4 miles/hr
The equation to find the time is:
time = distance / rate
Plugging in the values, we have:
time = (3.311*10^8 miles) / (7.7*10^4 miles/hr)
The units of miles cancel out, leaving us with hours as the unit for time.
time = (3.311 / 7.7) * (10^8 / 10^4) hours
Simplifying the exponent terms:
time = (3.311 / 7.7) * 10^(8 - 4) hours
time = (3.311 / 7.7) * 10^4 hours
To express the answer in scientific notation, we write it as:
time = 0.429*10^4 hours
Therefore, it will take approximately 0.429*10^4 hours for the asteroid to hit Mars.
An asteroid is heading toward Mars at the 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? Write the answer in scientific notation, expressed to the exact decimal place.(1 point)
