How does a mobile move in a rectilinear manner?
According to the summary, the mobile moves in a rectilinear manner based on a position graph as a function of time, showing a straight line for constant speed and uniform movement. It starts from a position and moves in the positive direction of the references.
What is the speed of the mobile in kilometers per hour?
The speed of the mobile is calculated as 36 kilometers per hour, which is equivalent to 0.6 kilometers per minute. This conversion allows for a better understanding of the mobile's movement in terms of speed.
Where will the mobile be located after two hours?
After two hours, the mobile will be at a distance of 72 kilometers from the origin. This information is derived from the constant movement of the mobile in a straight line trajectory.
How far is the mobile from the origin at a certain time?
At a certain time, the mobile will be located 18 kilometers from the origin. This distance is a result of the mobile's continuous movement in a rectilinear manner.
How long does it take for the mobile to reach a distance of 18 kilometers?
The time it takes for the mobile to reach a distance of 18 kilometers is calculated as 30 minutes. This time frame is determined by the speed and trajectory of the mobile's movement.

Kilometers over one equals 30 minutes
- Denominator simulators can be expressed as kilometers over one.
- If the denominator is alone at the bottom, it is equivalent to having a 1.
- By applying the rule of extremes, canceling out kilometers gives a result of 30.
- The remaining time is 30 minutes.
- The final result does not need to be written down.
