There are a lot of equations that relate time, velocity, distance, momentum. The equations contain variables in various units. For example
time - second
velocity - meters/second
distance or length - meter
momentum - this is a derived SI unit - Newton-second
Now, how you put them together depends on what you're trying to achieve. For example, the time to travel some distance
D = V x T where D is the distance, V is the velocity, T is the time
The units you express V and T in will determine D. For example, if V is miles/hr and T is hrs, D will be in miles. Miles can be converted to meters or kilometers, time can be converted to seconds.
This is the best I can do with what you asked. If you need more help, plese ask.

velocity = distance * time
work out from the equation above to find time and distance
momentum = mass * velocity
