Question

A comet is traveling in outer space with a velocity of 2000 m s. How long will it take to travel 300.000 meters?

Answer 1

Answer:

.15s

Explanation:

Follow the units here. If you divide 300.000m by 2000m/s then you'll end up with the meters reduced and just the seconds. So that's what you do to get the time:

(300.000m)/(2000m/s ) =

(300.000/2000)(m•s/m) =

0.15s
