Question

Please help me! it is due tmr :(

Answer 1

To answer this, you need to know the distance to the moon in km which is 384,400 km (that should be given in your class text, or you can google it). Then, you'll convert that distance to hours using the km/h number given.

Since your rocket ship can travel 2.8x10⁴ km/h, multiply 384,400 km by (1h)/(2.8x10⁴km). The km units cancel, and your result will be the number of hours the trip to the moon took.
