Answer:

Microwave takes 13.67μs to travel from cell phone to tower

Step-by-step explanation:

Given data:

Distance traveled by microwave from cell phone to tower =
(4100 m)/(3 x 10^(8) m/s)

We know that the microwave is an electromagnetic wave and the velocity v of electromagnetic wave is 3 x
10^(8) m/s.

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

Velocity =
(distance)/(time)

Hence, time =
(distance)/(velocity)

Therefore, time of travel of microwave =
(4100 m)/(3 x 10^(8) m/s )

=
(4100 m)/(300 x 10^(6) m/s )

= 13.67 x
10^(-6) s

= 13.67 μs (μs is microseconds)

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