Question

The moon is about 3.6 * 10⁸ meters away from earth. A commercial airplane flies about 300 kilometers per hour, how many hours would it take a plane to fly this distance?

A) 1.2 x 10¹0 hours
B) 1.2 x 10⁶ hours
C) 1.2 x 10² hours
D) 1.2 x 10⁴ hours

Answer 1

To calculate the time for a plane to fly from Earth to the Moon, you divide the distance to the Moon (360,000 km) by the speed of the airplane (300 km/h), resulting in 1.2 x 10⁴ hours.

Step-by-step explanation:

The question is asking how long it would take a commercial airplane flying at 300 kilometers per hour to travel the distance from Earth to the Moon, which is approximately 3.6 × 10⁸ meters (or 360,000 kilometers). To find the number of hours it would take, we divide the total distance by the airplane's speed.

First, we need to convert the distance from meters to kilometers: 3.6 × 10⁸ meters is equal to 3.6 × 10⁵ kilometers. Then we can divide this by the airplane's speed:

Hours = Distance ÷ Speed = (3.6 × 10⁵ km) ÷ (300 km/hour) = 1.2 × 10⁴ hours

So, the correct answer is D) 1.2 × 10⁴ hours.
