Second, the distance between two trains is the sum of the distance traveled by the train traveling west and the distance of the train traveling east.Uniform motion refers to motion that does not change.You would expect to find uniform motion on the interstate with cars traveling at a 'uniform' speed of 70 mph with no traffic lights to slow traffic.To solve uniform motion problems, you will be given two of the variables mentioned and will need to use algebraic methods to solve for the third.If you aren't given two variables, you can't solve uniform motion problems. Now, just substitute the known values into the formula and solve.Lastly, the time duration the two trains traveling are equal. We let be the travel time of each plane (remember, they are equal).Since the distance is the product of the rate and the time, the distances traveled by the east-bound and west-bound train is and respectively. The second problem is just almost the same as the first problem.In how many hours will they be 1260 kilometers apart?Before we proceed with the solution, let us take note of the following.Method: variables given: r = 150 fps, t = 300 s (notice the conversion from minutes to seconds to match the rate units given). Substitute known variables and solve: d = 1.5(300) = 450 Given our solution, the bug will travel 450 feet in 5 minutes. The formula for uniform motion problems is d = rt, which means distance is equal to rate times time.Sometimes, uniform motion problems are complex, involving more than one item in motion. Convert 1.6 hours into hours and minutes to get 1 hour and 36 minutes. Convert 1.3 hours into hours and minutes and get 1 hour and 20 minutes (rounded). You must be given two of these variables to solve a uniform motion problem.
