Please help me

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

Answer 1

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.
