Question

A spaceship to the moon covered the 386,400 km in 72 hours. What was the average speed?

Answer 1

1.49 m/s; 5.367 × 10⁶ m/hr

Step-by-step explanation:

Calculations: (This was my thought process, sorry)

386400 km ÷ 72 hr ≈ 5367

5367 × 1000 = 5.367 × 10⁶

5.367 × 10⁶ ÷ 3600 ≈ 1.49 m/s

About 5367 km/hr or 5.367 × 10⁶ m/hr or 2.592 × 10⁵ m/s

Have a great day!
