So if you want to solve for time you can divide both sides by 3m/s and then on the left side they cancel out on the right hand side this is going to be equal to720 divided by 3 times meters then m/s of the denominator, if you bring it out to the numerator you take the inverse of it so that's m, meters was on top, so 720 meters and now you're dividing by m/s and that's the same thing as multiplying by the inverse times s/m and so what you're going to get here the meters are going to get 720 divided by three seconds so what is that, 720 divided by 3, 72 divided by 3 is 24, so this is going to 240 this part riight over is going to be 240.
