A rocket powered sled on a track in the desert, is equipped to travel at a constant velocity of +358.0 km/h. How long does it take the rocket sled to travel +4.56 km in seconds?

V=displacement/time
358.0=4.56/time
time=4.56/358
time = 0.01273 hours
1hr=60minutes
1min=60 seconds
1hr=3600 seconds
time = 0.01273 hours * (3600seconds/hr) = 45.85 seconds

We first list out what we know.
Initial Velocity(Vi) = Final Velocity(Vf) = 358 km/h (Since we have constant velocity)
Acceleration = 0 m/s2 (Constant velocity)
Distance(D) = 4.56 Km
Time = ?
We can solve for time by cancelling the km in our velocity.

4.56km / (358km/hr) = 4.56km * (1hr/358km) = (4.56hr / 358) = 0.013 hr
0.013hr * 60 minutes * 60 seconds = 45.855 seconds

Solution:
The qestion is for the students to convert one hour into how many seconds:
1 hour = 60 minutes = 3600 second, therfore, the speed of the rocket sle in km/s is
v=358 km/h = 358.0 km/(3600 seconds) = 0.09944 km/s
the time required for the rocket sled to travel the 4.56 km is
t = 4.58 km / (0.09944 km/s) = 46.01 seconds
t=
