Hey guys, so I'm currently doing summer homework for my first physics class and I came across this problem
Simply:
Δt = (4.0*10^2meters)/(16meters/second)
Can someone give me a step-by-step process? I'm honestly really confused and would sure love the help. Thanks!
Simplifying velocity?

You're confused because you are not using proper notation for the physics. And that's simply distance = average speed X time traveled; S = Vavg T. And in this case you're solving for T = S/Vavg = 4*10^2/16 = 25 seconds. ANS.

The meters cancel out, and because 1/second is in the denominator, it fills to be second in the numerator. So, the units are correct, and all you need to do numerically is the division.
Tracking and cancelling the units is an important step in the process. That keeps you from doing stuff like trying to get a velocity, and ending up with units of seconds/meter.
