Question

The mass of a freight train is 9.98 ⋅ 10to the power of 6 kilograms. The mass of an aircraft carrier is 7.3 ⋅ 10 to the power of 7 kilograms. Approximately how many more kilograms is the mass of an aircraft carrier than the mass of a freight train? Show your work and write your answer in scientific notation.

Answer 1

The mass of the aircraft carrier is approximately 6.30 × 107 kilograms more than the mass of the freight train.

Step-by-step explanation:

To find the difference in mass between the freight train and the aircraft carrier, we subtract the mass of the freight train from the mass of the aircraft carrier.

Mass of the aircraft carrier = 7.3 × 107 kg

Mass of the freight train = 9.98 × 106 kg

Difference in mass = 7.3 × 107 kg - 9.98 × 106 kg

Difference in mass = 6.30 × 107 kg

Therefore, the mass of the aircraft carrier is approximately 6.30 × 107 kilograms more than the mass of the freight train.
