Answer:

0.00117 s

Explanation:

The altitude is the distance traveled by the radio signal

Distance = 350 km = 350000 m

The radio signal travels at the speed of light

Speed = 300000000 m/s

The time taken will be calculated as shown below

Time = Distance/Speed

Time = 350000/300000000

Time = 0.00117 s
