The radius is 100 miles . . . so the diameter is 200 miles (100 miles in the direction of the transmitter and 100 miles going amethod.At 40mph it takes 5 hours to drive 200 miles, therefore you might listen to the terminal for 5 hours.

You are watching: A radio station has a radius of 100 miles

You deserve to listen to the station for 5 hours before the signal fades

### More explanation

Acceleration is rate of adjust of velocity.

a = acceleration ( m/s² )

v = final velocity ( m/s )

u = initial velocity ( m/s )

t = time taken ( s )

d = distance ( m )

Let us now tackle the problem!

Given:

Radius of Signal = R = 100 miles

Speed of Car = v = 40 miles/hour

Unknown:

Time Taken = t = ?
