Answer 1

The last one im on the same assignment lml

Answer 2

Answer: 10 meters per second

Since it is the speed of a fast moving object, using the time units of minutes and hours would not make sense. Likewise, using a measurement of a large distance during a short amount of time (km/s) would not make sense either, as the number would be inconvenient to use.
