A microwave travels 4100 meters from your cell phone to a cell tower. How long does it take to reach the tower?

Microwave takes 13.67μs to travel from cell phone to tower

Explanation:

Given data:

Distance traveled by microwave from cell phone to tower =

We know that the microwave is an electromagnetic wave and the velocity v of electromagnetic wave is 3 x m/s.

In general, to determine time of travel from distance and velocity given, we divide distance traveled by velocity. That is

Velocity =

Hence, time =

Therefore, time of travel of microwave =

                                                                 =  

                                                                 = 13.67 x s

                                                                  = 13.67 μs     (μs is microseconds)

Hence microwave takes 13.67μs to travel from cell phone to tower.
