To calculate the time it will take for the asteroid to hit Mars, we can use the formula:
Time (in hours) = Distance / Rate
Substituting the given values:
Distance = 3.311x10^8 miles
Rate = 7.7x10^4 mi./hr
Time = (3.311x10^8 miles) / (7.7x10^4 mi./hr)
Dividing the distances and subtracting the exponents, we get:
Time = (3.311 / 7.7) x 10^(8-4) = 0.429 x 10^4 = 4.29 x 10^3
Therefore, it will take approximately 4.29 x 10^3 hours before the asteroid hits Mars.
an asteroid is heading toward mars at the rate of 7.7 x 10^4 mi./hr if the asteroid is 3.311x10^8 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
